About Kupinji

Kupinji makes one thing: the long-sleeve tee. We think that's enough to be great at it.

Kupinji started with a simple frustration — finding a good plain tee meant either paying brand markup for a logo, or rolling the dice on mystery fabric. So we cut out both: our own factory, our own fabric sourcing, and tees that ship straight from our production line in China to customers around the world.

Everything about the product is written on the page. Weight in GSM. Fabric composition. Fit and sizing. No hype, no invented technology — just an honest shirt at an honest price.

We sell two ways: retail, one tee at a time, and wholesale from 36 pieces for teams, print shops and resellers. Same factory, same quality, both channels.

How we work

• Factory direct — We make and ship ourselves. Fewer hands, lower prices.
• Numbers you can check — Weight, fabric and fit are stated — and true.
• Plain answers — Clear pricing, clear shipping, replies within one business day.
