My favorite for sublimation
My go to brand for sublimation, everytime. You can't go wrong. Great quality tumblers. They will hold ice longer than any other off brand I've tried. Rims won't leak as long as you have them on correctly.

I love this brand
I just started doing sublimation cups and would buy them at hobby lobby, but the market is saturated and they’re always out. So, I just bought a 4 pack from this company to try. They turned out great, I just don’t like metal straws, so I buy plastic ones separately. Then I went up to the 8 pack and again, wasn’t disappointed. They don’t sweat, the ice stays solid and the water stays cold overnight. I see sub cups and haven’t had anyone complain yet. They also sub really well. This is now my go-to company for sub cups.
