Great coffee mug, I love the ceramic over stainless, but PLEASE make a leak-proof lid.

I love this sip tumbler so much. I got the Shell color and it came out to be a very light pink one, which is my fav! And I didn’t expect it to be ceramic-coated inside (maybe because I havent read the description clearly). But i feel like it makes my drink taste better than any other stainless steel. There’s a lot of cute color so I probably buy more for my tumbler collection ^^

I love the sip tumbler. I needed a travel cup that kept my drink (I only drink matcha) warm when I got to work and beyond and this fit the bill. It keeps my matcha warm for a really long time. I was using the porter travel cup for the longest time and it never kept my drink warm. This also fits in the cup holder in my car too. This tumbler is teacher approved!
