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.
