Description
Want to take another step toward zero-waste but always forget your reusable mug at home? This sleeve fits in your bag and is always ready without needing to be washed after each use. It's perfect for coffee and tea lovers both, and features a sleek and stylish design that is custom-designed to fit Starbucks™ cups.

Printing recommendations:
Inside brim for better adhesion while printing
Supports not necessary
Color changes at the bottom and top of each grip ring
Use ABS, ASA, or PETG, since PLA will get pliable at coffee cup temperatures
