MALTSKY Collapsible Silicone Coffee Cup (Max Capacity 550ML) - Reusable Folding Travel Cup Gift Mug for Home Camping Outdoors - 3 Adjustable Sizes to Suit Everyone's Needs (Grey)

I could say that this coffee cup is the best I have ever used; the climbing buckle makes it really convenient to take it anywhere. And it also has three adjustable sizes for the coffee lover. I have bought several collapsible coffee cups before, they always have leaking issue. But this one can be safely stored in my bag. Really pleased with this purchase.

So excited when this arrived, but the box looked either already used, or tampered with. Still, the cup looked fine. Went to use it on Sunday evening and ended up with burnt fingers and a wet shirt. A hidden gash in a fold was leaking coffee all over the place.As this was my first order from this company and this type of purchase, i was most disappointed to say the least. Unsure if this was a faulty cup, but in reality, i suspect this was already returned and sent out to me as i asked for next day delivery. I would like to be greener, but having spent more time reviewing all these collapsible mugs, this seems to be an issue with them all. I'll wait until they can make one that actually does what it says. This is sadly not that cup. Returned for a refund. Please don't waste your money on this, especially if it's not on sale!

Really good replacement for polluting, disposable coffee cups. Does not leak!!! Collapses exactly as promised so less space/weight in commuter bag. Slightly less stable( than the disposable kind) when fully extended, but not a problem.

Good collapsible mug. Use mine for my daily coffee from Pret. (Their only complaint is that it doesn't fit in their machine so they have to make my coffee on the side). The top seals well so no coffee spilt.It's lightweight and fits snugly in my handbag once collapsed.Only slight niggle is that it's not as sturdy as another collapsible mug that I had.

No more rubbish for landfill. This cup is collapsible and fits into pockets and bags. It’s completely drip proof and can be carried comfortably without burning hands when filled with hot liquids.

I received the cup in the next day after booking，so the delivery is really efficiently，and the coffee cup can be used in many places ，can be collapsed in different sizes and very functional ，it looks great as well.highly recommend！

It is a very good cup! Colour is just fantastic. It doesn't leak and it's a great tool to save environment!It is sometimes tricky to fold it back or to make size smaller while having drink inside.

The drink not the drinker! lolPros - well made and robust, nice colour, easy to collapse/open, compact and lightweight so easy to carry around.Cons - would only take the smallest size coffee from most vendors (that's fine for me but not everyone), if possible don't fill to the top as when you put the lid on some will spill out, if you have to suck the drink out of the mouthpiece the cup collapses.
