Thank you so much for your support, Marilu!
Probably one of the best cups I've purchased! Keeps my drink cold all day and it's such a sleek looking cup.
That is AMAZING to hear, Alicia! Thank you so much for your support :)
I got this cup because I work in the health-care field and it seemed durable enough to be toted around with me all the time. Unfortunately I dropped it on the floor once and it already has a scratch/gouge in the lid. It seals well though because it only spilled a little and that was from the top where the straw goes in.
