23oz/680ml Glass Tumbler with Straw and Lid - Matcha Leak-Proof Portable Travel Water Glass Cup for Smoothies, Iced Coffee,Matcha and Cold Beverages - Durable and Eco-Friendly (Greywith Sleeve)

Perfect size for matcha or iced tea on the go. Lid fit snug and cup is cute.

It’s an ok cup. I like that it’s glass. The grip doesn’t help with anything but keeping my fingertips from freezing. My ice melts pretty quickly. It would be a great buy for $7.99. The size is good! I use it everyday and get my money worth.

I wanted a glass tumbler that fit in my vehicle's cup holders and this works perfectly. I make a protein smoothie with it in the mornings and take it to work. I'm not very careful with it, and it hasn't cracked or broken. I really like that cap slides on and off instead of being a screw top, and it hasn't leaked. I am hoping they make a larger version (maybe 32 oz) and I'd really like a sleeve for it.

Absolutely love these cups. They are stylish and durable. Want to buy more

Quality has definitely gone down. I have another blue polar cup that's 13oz and was hoping for the same quality here. This glass is thin, weak, and broke on my second use. It completely shattered on the bottom when it touched my counter briefly - I didn't even drop it. I included a photo of my other blue polar glass which is much better quality for comparison. I can't recommend this brand anymore as it's clear the quality has gone down which is a shame, I couldn't believe how easily the glass broke.
