Collapsible Coffee Cup，Portable &Reusable Coffee Cup，Travel Coffee Mugs Collapsible with Lid Fits in Your Pocket Or Bag for Business, Home, Travel, Camping（12oz 350ml, Leak Proof, BPA Free） (Blue)

I bought this because I'm trying to start reducing my plastic usage and also try to take my own drinks rather than purchase them out. This is perfect, it folds perfectly to fit into my bag and isn't tricky to disassemble and fold back down. I'm only dropping down a star because I wanted to reduce plastic and this was delivered in so much of it! Otherwise, it's amazing. Couldn't recommend it more.

Fabulous concept. Folds easily. The interior stained after first use and seemed quite absorbent. I thought it was ok for the price and I’d just replace if it got too tainted with coffee taste. Then in about the 10th use if split on the thin edge that collapses. So all in all not a very “green” product given it’s short lifespan.

I like it - collapses well into a small shape and fits in my briefcase

Good idea fits nicely in my work bag. Sadly I found that when drinking from the spout the cup collapsed in on it self. So o didn't get on with it and gave it away. My wife kept hers and drinks from it with the lid off.

Bought as gift. Very happy with product and delivery time

Compact and fits easily into a handbag.

Does what I needed it for

I gave one of these as a present to my son who is very pleased with it. He travels a lot, regularly uses the cup, and says it gains him a discount in coffee shops, folds up small, and the seal is good. His wife is so impressed that she has asked for one as a present for herself. I've only used one once, and found it a bit awkward to unfold and then fold up when I'd finished the coffee. But I expect it will get easier the more I use it, there was no leakage from the dregs of the coffee in my bag, and I think it's well worth persevering for environmental reasons and because it saves money. I also find the design attractive, and am relieved that the silicone didn't flavour the coffee at all.
