Company profile · Longgang District, Shenzhen, Guangdong, China · 5 October 2026
Most craft-supply factories advertise relaxation. Very few can show you the press. That distinction is the whole reason to look at Joysine: a kit lives or dies on the legibility of the numbered zones printed on its canvas, and printing is the one step this company has controlled since day one.

Where the company came from
Joysine began in 2013 as a small design studio doing one narrow job: taking a family photograph and turning it into a hand-numbered painting template. That work is printing work — image separation, colour matching, halftone decisions, register control. The studio did it well enough that gift shops kept ordering, and overseas e-commerce sellers started asking whether the same team could handle five hundred units instead of fifty.
The company's published timeline picks up the thread from there. 2016 brought its own production line and the first export orders to Europe and Australia. 2019 added diamond painting output alongside white-label services for online brands. 2022 saw the move to the 2,000 sqm Longgang facility with automated printing and a three-stage inspection routine. Today the same floor supports retail supply, wholesale, OEM and dropshipping programs.
Read in reverse, that timeline explains the quality argument. A paint-by-numbers canvas with faint numbering, zones that are too small to paint inside, or a colour key that doesn't match the pot labels produces a frustrating afternoon and a muddy finished piece — regardless of how decent the acrylics are. A supplier that owns the press owns those failure modes.
What it puts on the line
Numbered canvas kits
A standard Joysine paint-by-numbers kit contains a pre-printed linen-blend canvas with numbered fields, pre-mixed high-pigment acrylic paints in sealed pots labelled to match those numbers, three brush sizes, and a printed reference chart. Difficulty is set by zone size and palette length rather than by subject matter, so a first kit can run twenty colours while a challenge piece runs forty-eight. Sizes start near 20×30 cm for impulse shelves and go up to 80×120 cm for statement canvases, with rolled or framed options.
Full-drill diamond art
The 5D diamond painting line pairs a high-tack adhesive canvas with faceted resin drills cut to a consistent size, supplied full-drill — every symbol on the chart gets a stone, no bare background. Round drills are faster to pick up and more forgiving for beginners; square drills butt together edge to edge for a continuous mosaic surface with no visible gaps, which experienced crafters tend to prefer. Each box carries the working kit: applicator pen, wax, tray, tweezers, storage bags, and spare drills sealed in every colour bag so a short count mid-project doesn't end the piece.
Photo-to-kit and private label
Custom work is where supplier quality varies most, because most catalogue software handles it badly: an auto-filter flattens a portrait into thirty indistinct zones and the finished painting looks nothing like the photograph. Joysine states that its design team re-works each submitted image into a paintable template, adjusting zone boundaries and matched paints by hand. For brands, the same production line runs OEM and ODM programs — your logo on the box, canvas and manual, bespoke packaging on larger runs, and dropshipping support for sellers who hold no stock.
Inside the 2,000 sqm floor
The operating claims are narrower, and therefore more checkable, than the usual supplier brochure:
- One inspection per batch, in three passes. Print clarity, paint colour match, and packaging integrity, checked on every production batch rather than spot-audited monthly.
- No intermediary. The company sells from its own line instead of reselling, which shortens both the price chain and the loop between a complaint and a correction.
- Free sample, then fifty units. A single kit or a 50-unit test order is treated as a normal job, not an inconvenience, before a buyer commits to volume.
- Materials. Water-based, non-toxic acrylics described as child-safe, with recyclable packaging as standard rather than an upgrade.
- Named contact. One account manager per order and multilingual support before and after the sale.
Geography matters here too. Bantian sits in Longgang, on the eastern edge of Shenzhen's manufacturing belt, with canvas mills, pigment suppliers and Yantian port container logistics within easy reach — which is why two-week restocks and DDP freight to the US, EU and Australia are realistic rather than aspirational.
Wholesale and OEM terms, in numbers
| Minimum order | 50 units, and mixing designs plus sizes inside one order is standard practice |
| Price tiers | Volume discounts begin at 50 units with deeper cuts from 500; the company claims pricing up to 50% below typical distributor rates |
| Order types | Starter, premium, branded and large-format lines |
| Defects | Replacement or refund within 30 days on photographs alone, with no claims paperwork |
| Freight | Sea, air or express courier; DDP options for the US, EU and Australia |
| Speed | Quotes typically within one business day, restocks in as little as two weeks, end-customer delivery in 7–15 business days tracked |
Marketing assets — product photos, banners, social templates — are supplied at no charge, and private-label artwork is included on wholesale orders rather than sold as an add-on.
Six checks before you order from anyone
These work on Joysine and on every alternative quote sitting in your inbox. Apply them uniformly and the differences between suppliers become obvious within a week.
- Ask to see the press. Request a close-up video of numbering being printed onto canvas, registration marks included. A genuine printer sends it the same day. A reseller asks why you need it.
- Order one sample, then wait. Judge paint opacity in a single stroke and drill faceting under a lamp immediately — but leave an unused canvas sealed for thirty days in a warm room and check whether the adhesive is still tacky. That is the failure nobody discloses.
- Break the colour matching on purpose. Pick a design with three adjacent similar tones and paint them in order. Weak colour separation shows up as a flat, muddy region no amount of careful brushing can rescue.
- Ask what happens on a short count. Diamond kits should carry spare drills per bag. Confirm the replacement path for a colour that runs out with a fifth of the canvas still open.
- Check the licensing exposure. Catalogues heavy with celebrities, film characters and licensed artwork are a takedown vector on Amazon and Etsy. Ask which designs the factory owns outright, and keep that list for your own storefront.
- Put tolerances in the purchase order. Acceptable print misregistration, minimum paint volume per pot, packaging specification. A 30-day guarantee is a legal term only if a defect is defined; otherwise it is a courtesy.
Frequently asked questions

Catalogue sizes, price positioning and material safety claims are the manufacturer's own statements; confirm them in writing on the purchase order before committing volume. The founding date is consistent with Shenzhen registration records for 深圳市玖晟科技有限公司 (22 October 2013), though some third-party B2B directories still list it as 2015.
