It’s also microwave-safe! Note that the 12-ounce size does not include a straw, but both the 16-ounce and 24-ounce sizes do.

BuzzFeed Shopping editor Danielle Healy writes: “This is of the first zero-waste swaps I made and I’ve never looked back. If you buy to-go coffee – whether you’re jet-setting or just grabbing a mid-day pick-me-up — this cup is a must-have. So long as you remember to bring it, it’s all the convenience of to-go coffee with none of the waste. It’s leakproof and, when you’re all done, it collapses down teeny tiny and can be tossed back in your bag. Oh! And it comes with a straw, so all you iced coffee lovers can get in on the action, too.”

Promising review: “I love this cup — I am very glad I decided to get one as being a flight attendant I don’t always find paper cups in the hotel rooms and ewwww, don’t always want to have to clean a mug in the room. Having this is great! I like that it comes with a holder much like the cardboard ring that coffee shops provide — I always use it and it helps the cup be extra sturdy!” —AuthorEP
