Buy it, you won't regret it!

I absolutely love these cups! specifically the simple modern ones. I bought one and my mom uses it now so i bought this as a replacement and I will definitely be buying another one!! Having owned several Stanley's i prefer Simple Modern best. It actually keeps my ice overnight and doesn't leak!!

Literally my favorite!

For me, the 30oz is the perfect size. It's not overly big and it's not too small. I have it in both black and the dark green and I love it so much. The dark green one was my first and I had it so long that the bottom has now become a little scuffed. I'm talking years. So I bought the black one next and I can tell you, these are the two that I reach for the most. I know a lot of time and creativity goes to the 40oz but I'm begging you to add some variation and attention to the 30. I'm a huge fan. Please don't neglect this one! Die hard fan!Thank you for making my favorite cup!

My experience

I've been using simple modern for about 3 years now and I'm obsessed. The only brand I recommend and hype up to anyone truly amazing quality, thanks for making being just a girl a little easier (I'm 21) and I live by that saying “I'm just a girl” because it's so true
