KeepCup Cold Cup - Brew Cork Tempered Glass Ice Coffee Tumbler with Recovered Cork Band, Lid and Straw - 16oz (454ml)

Second cup that has been delivered with obvious previous use including : water marks, ring at bottom of cup and smelling of coffee. UNSANITARY and not marking products as Used for resale.

Plastikowa słomka (łatwo zamienić na szklaną lub metalową) jest bez oznaczenia jaki to materiał. Plastikowa pokrywka z silikonowymi uszczelkami dobrze się trzyma i nieźle chroni przed rozchlapywaniem ale nie ochroni przed rozlaniem (brak informacji z jakiego plastiku jest pokrywka) choć brak całkowitej szczelności to brak wytwarzania podciśnienia co utrudniałoby picie przez słomkę. Kubek-szklanka jest dość ciężki i jest to ten sam co keepcup polecany przez baristów (do kawy) - pokrywki pasują zamiennie.

So in love with my new keep cup. It works great for iced lattes and also the perfect size to have my pre workout in.It’s super easy to clean, would definitely recommend to others.

The double-wall design doesn’t really work cause I’ve been trying it with cold water and the whole tumbler has condensation making it slippery and leaving water marks on tables.The straw is plastic so it gives some taste to water.The design is cute but it’s not functional and doesn’t do what is stated in the description.

I'm a bit mixed with this, it's not bad overall but I don't like the wide plastic straw it comes with, more of a Boba straw, I removed this and use a regular sized glass straw I already had, the internal cup is a single glass that extends a bit above the grip, then there's a plastic cup that snugs up to a groove under the grip which provides the extra wall, I feel like this won't last but will see.Everything can be easily seperated and cleaned, would have been nice to get a brush for the straw for people that use it, the included straw could have slightly more rounded edges.The seal around the straw is ok but doesn't create a full seal so it can leak if tipped over too much or is shaken about.It doesn't work great to keep stuff cold or hot, I made matcha this morning and it was cold by the time I got to my desk at work (maybe 40ish mins), I also had an iced latte in it today and filled the whole glass up with ice at 10am, by 12 it was all melted, but does help reduce build up of condensation on the outside (note only reduces, not prevents).Overall it's decent as a reusable travel cup and bonus for having glass where liquids are, price could be better, strangely my included paper receipt stated a price that was approx 70% less than what I paid...
