Brümate sent me some of their cups a couple months ago. I didn’t expect much because it’s just a cup, right? I have used them every day and they are officially my favorite! They feel so nice and Hugh quality. The bottom of the straw is stainless steel but the top is soft so your drink won’t taste weird and you won’t hurt a tooth on it! The lid LOCKS. This is such a handy feature on the go. If you’re like me and like to mix in powders and electrolytes, just lock the lid and shake! This weekend, 7/4 to 7/6 use this link and code CLASS to get 20% off most items in their website !
