These are non-tapered straight blank 20oz or 30oz white skinny tumblers that include a straw and ships in individual white boxes.
Vacuum seal keeps liquid fresh and drinks cold! Leak Proof Lids!
These are for SUBLIMATION purposes. We have the same tumblers for non sublimation available as well.
Some dishwashers use high heat to wash which may possibly causing the ink to reactivate. I recommend to my customers to hand wash!
I press these by placing the image down and then turn tumbler and press the other side as well!
Also available in packs of: 10, 20, 30
