Summary

I like to keep a coffee sleeve handy, in case I need a pick-me-up. Using the xTool heat press allows me to customize my own. 

Use these as gifts, giveaways, promotions. There's no limit.

Sublimation can be done on neoprene sleeves or regular cardboard ones. Sublimation on black will not be visible. The darker the original material you sublimate on, the harder it will be to see, so I suggest using white.
