Joysine: Inside the Shenzhen Factory That Makes DIY Art Accessible to Millions

Not every household name starts on a supermarket shelf. Some begin in small design studios, fueled by a simple belief — that creating art should be open to everyone, not just the talented few. Joysine, a paint by numbers and diamond painting manufacturer headquartered in Shenzhen, China, is one of those companies. Since 2013, it has grown from a custom photo-to-canvas workshop into a full-scale DIY art kit factory supplying retailers, e-commerce brands, and individual crafters across more than 30 countries.

This article takes a closer look at who Joysine is, what they manufacture, how their factory operates, and why hundreds of brands worldwide have chosen them as their go-to OEM and wholesale partner for paint by numbers and diamond painting kits.

A Brief History: From Photo Studio to Global Manufacturer

Joysine was founded in 2013 in Shenzhen — often called the hardware capital of the world — but with a decidedly artistic mission. The company started as a small design studio that specialized in converting family photographs into hand-numbered painting templates. Local gift shops were the first customers, followed quickly by overseas e-commerce sellers looking for a supplier willing to treat a 50-unit order with the same attention as a 5,000-unit one.

That responsiveness filled a gap in the market. Rather than remaining a design-only operation, Joysine invested in its own production infrastructure. By 2016, the company had opened its own manufacturing line and began fulfilling its first export orders to Europe and Australia. In 2019, diamond painting was added to the product catalog alongside white-label services tailored for e-commerce entrepreneurs.

By 2022, Joysine had expanded into a 2,000-square-meter facility equipped with automated printing systems and a three-stage quality inspection process. Today, the factory serves over 500 brands, retail stores, and startups through its retail, wholesale, OEM, and dropshipping programs.

What Joysine Manufactures

Joysine operates in two core product categories — both designed around the principle that anyone, regardless of artistic skill, can create something beautiful with their own hands.

Paint by Numbers Kits

At the heart of Joysine's business is its paint by numbers kit line. Each kit includes a linen-blend canvas with precision-printed numbered zones, a complete set of pre-mixed high-pigment acrylic paints, and a multi-size nylon brush set. The company offers everything from beginner-friendly kits with larger numbered zones for children to advanced 48-color challenges for experienced hobbyists.

What differentiates Joysine's paint by numbers kits from generic alternatives is the printing quality. The factory uses high-resolution canvas printing technology that ensures crisp, smudge-free numbers — a detail that matters enormously when a crafter is matching a tiny section of the canvas to its corresponding paint pot.

Diamond Painting Kits

Since 2019, Joysine has also produced 5D diamond painting kits. These feature precision-cut resin drills in both round and square formats, paired with high-tack adhesive canvases that hold diamonds firmly in place. Every kit ships as a complete toolkit: applicator pen, wax, sorting tray, tweezers, and storage bags are included so the crafter never needs to source additional supplies.

Round drills are popular with beginners for their ease of placement, while square drills appeal to advanced crafters who prefer the tight, mosaic-like finish with no visible gaps between stones. Joysine manufactures both in full-drill format.

Custom Photo-to-Kit and Private Label Services

One of Joysine's strongest differentiators is its custom manufacturing capability. Individuals can upload personal photographs — wedding portraits, pet photos, family memories — and receive a fully personalized paint by numbers or diamond painting kit. For brands, the company provides end-to-end OEM and ODM services: from custom design work and packaging to logistics and dropshipping fulfillment.

Inside the Factory: Quality Control and Production Standards

Joysine's 2,000-square-meter facility in Shenzhen houses the entire production chain under one roof. Canvas printing, paint filling, diamond sorting, and packaging are all handled in-house — a decision that gives the company direct oversight of every step in the manufacturing process.

The factory operates a three-stage quality inspection system:

• Print clarity check — Every canvas is inspected to ensure numbered zones are legible, properly aligned, and free of printing defects.
• Paint color matching — Acrylic paints are verified against design specifications for pigment density and color accuracy before they're sealed into pots.
• Packaging integrity — Final inspection ensures all components are present, packaging is undamaged, and labeling meets the destination market's requirements.

The company also prioritizes safety and environmental responsibility. All acrylic paints used in Joysine kits are water-based, non-toxic, and certified child-safe. Packaging materials are recyclable, reflecting growing consumer demand for eco-conscious products in the DIY craft segment.

Why Brands and Retailers Partner with Joysine

Joysine's client roster includes craft shop owners, Amazon and Etsy sellers, gift brands, and educational suppliers across North America, Europe, Australia, and Asia. Several factors explain why these businesses choose Joysine over competing manufacturers.

Factory-Direct Pricing

Because Joysine manufactures every kit in its own facility, there is no trading company or intermediary adding margins. Buyers work directly with the production team, which means pricing reflects actual manufacturing costs rather than layered markups.

Flexible Minimum Orders

Joysine accommodates orders of all sizes. A startup launching its first product on Etsy can start with a 50-unit test order. An established retailer can scale to thousands of units per month with the same quality consistency. The company also offers free samples so buyers can evaluate quality before committing to a production run.

White-Label and OEM Expertise

For brands building their own product lines, Joysine provides comprehensive white-label services. This includes custom box design, branded packaging, proprietary design catalogs, and private-label documentation — all managed by a dedicated account manager with multilingual support.

Design Catalog Depth

With a catalog exceeding 50,000 designs — spanning landscapes, animals, florals, famous artworks, cityscapes, and seasonal themes — Joysine offers one of the deepest design libraries among paint by numbers manufacturers. This breadth allows retailers to curate collections for different demographics without needing to commission original artwork for every SKU.

The Growing Market for DIY Art Kits

The global DIY craft kit market has experienced significant growth in recent years, driven by rising interest in mindfulness, screen-free leisure, and personalized gifting. Paint by numbers and diamond painting sit at the intersection of several powerful consumer trends: the demand for accessible creative outlets, the popularity of meditative hobbies, and the shift toward experiences over material goods.

Joysine's positioning as a factory-direct manufacturer places it to capitalize on this growth. As more entrepreneurs launch craft brands on platforms like Amazon, Shopify, and Etsy, the need for reliable, quality-focused suppliers with low minimum orders and OEM capability has intensified. Joysine's business model — combining design expertise, manufacturing control, and brand flexibility — addresses these needs directly.

The Philosophy Behind Joysine

Joysine operates on a deceptively simple philosophy: art should not require talent to be enjoyed. A numbered canvas or a coded diamond grid removes the intimidation of a blank page. What remains is the meditative, satisfying process of filling in one small section at a time until a finished artwork emerges — something tangible that the creator made with their own hands.

This approach has practical benefits beyond aesthetics. Occupational therapists and art educators use paint by numbers and diamond painting to develop fine motor skills, patience, and confidence in both children and adults. The structured nature of these crafts makes them popular tools for stress relief and digital detox — a reason their popularity surged during and after the global pandemic.

For Joysine, the mission extends beyond manufacturing kits. The company measures success by the moment a self-described "non-artist" hangs their first finished painting on the wall and begins planning the next one. That moment — equal parts pride and surprise — is what drives the factory's commitment to quality, affordability, and accessibility.

Final Thoughts

In a market increasingly populated by dropshippers and trading companies with no direct connection to production, Joysine stands out as a genuine manufacturer — one that designs, prints, fills, and packs every kit within its own walls. Thirteen years after its founding as a small photo-to-canvas studio, the company has evolved into a trusted partner for hundreds of brands worldwide, while maintaining the hands-on, detail-oriented approach that defined its earliest days.

For anyone exploring the DIY art kit space — as a consumer, retailer, or entrepreneur — Joysine represents what factory-direct partnership looks like when it is done right: transparent pricing, consistent quality, and a genuine commitment to making creative expression accessible to everyone.
