Our manufacturing know-how.
From an existing mold and a new brand design to a completely new product shape, YIHUA helps art supply, stationery and gift brands develop products ready for their sales channels.
What we customize
Four routes to your own product collection
02 · Formula, color & decoration
Discuss color matching, drawing performance, stamp impressions, barrel printing and UV decorative stickers. Performance claims depend on the tested configuration.

Changing the stamp impression or printed artwork may not require a new plastic-body mold. A new external shape or structure can require new tooling. Every project's material, ink, safety testing, MOQ and packing are confirmed individually.
