About Us

Shenzhen KeySelf Technology Co., Ltd. ("DIYMYKEY") is a design and innovation studio based in Guangming, Shenzhen. We specialize in the research and development of keychain-related products, with a core focus on creating premium DIY resin crafting experiences.

What began with a single silicone mold has grown into a full ecosystem of tools, materials, and inspiration. While keychains are our origin, we now empower makers to create far more—earrings, decor, functional art—all through the versatile medium of crystal-clear resin.

At heart, we combine technical precision with creative joy. Every mold we engineer and every tool we source is designed to help you capture a moment, express an idea, or simply make something beautiful with confidence. We're not just supplying products; we're enabling personal stories, one pour at a time.
