KOFFI ® KUP - Double Walled Glasses 250ml (8.8oz) - Borosilicate Glass - for Tea, Coffee, Latte, Cappuccino, Beer & AeroPress (250ml)

Brilliant wee set of glasses. These are really good value and quality is of high standard. I've used for over a week now and they are the perfect size for making an Americano from a Nespresso machine. Keeps the coffee hot for a good while and look great. Highly recommend these. Just pay attention to the instructions.....do not put in a dishwasher or leave submerged.....they are handmade so you need to be careful with them. Very satisfied.

As well as looking stylish and feeling great in your hand, they fulfil their practical purpose of insulating liquid very very well. I often leave my lungo or espresso lying round for 10 minutes by accident, and now it's still lovely and hot when I get round to drinking it. They are very light, but still feel solid and high quality.

Great cups aesthetically BUT you cant put them in the dishwasher or leave in the washing up bowl as the gap between the two layers fills with water which you cant remove!​

I bought these having been served coffee in them at a Swedish restaurant and ordered 8. My first wash I discovered an issue in that there is a small hole in the bottom, obviously how they are made that is filled with resin to make them air tight. This was missing on one and so it filled with water on Washing. It is then impossible to get rid of waging up reside inside. This caused me to check the others and I found three out of the eight defective . Not impressed to be needing to return two packs as I won’t get a refund until returned and I didn’t keep the box sent in!!!! Won’t be buying again. Having read reviews I can see others have had same issue

I was pleasantly surprised to receive two glasses, which represents excellent value for money.The glasses are rather more robust than many double-walled glasses on the market, and feel nice and chunky. They fit nicely under my Illy Francis Francis coffee machine. I use them almost exclusively for caffe latte: 200ml of milk, a tiny piece of molasses sugar, 100 seconds in the microwave and a shot of Illy Dark Roast from the machine. It stays nice and hot for about 20 minutes.The weak point of all these double-walled glasses is the little silicone valve in the base. Sooner or later it fails, so I'll just have to see how these glasses get on, in the long term. That's provided my wife doesn't drop one, which led to me buying this pair of KOFFI KUPs.PS: Don't put them in the dishwasher! My wife did, and the inner insulating space filled with water. When I read the literature, it specifically said "do not put in the dishwasher".

I give it 3 stars because I rate them 5 stars and 1 star at the same time.5 stars because they feel fantastic, are lovely to drink from and look really great.1 star because NEVER EVER SUBMERGE THEM OR DISHWASHER THEM! Now to be fair there is tiny writing on the box to say as much but you don't expect to have the warning on the box. There is a little hole in the bottom of the cup which allows for expansion and contraction of the air inside. If you submerge of dishwasher them you end up with dirty water inside the cup which you have a nightmare time getting out.Since then I have had to wash out with just using a damp cloth, not the end of the world but still a bit of a pain when you forget and the coffee residue dries, especially after a cappucino!

I ordered a set of two. The product itself is great and is a lovely design, however, one of the glasses arrived with a couple of small marks/indentation on the side of the glass and after trying can not be removed.

These are super elegant and look better in real life than in the photo. They are excellent value for money and a great way of serving hot drinks - they'd be ideal for a hot toddie, they are also ideal for coffee, hot chocolate, etc. They are comfortable to hold and are really well insulated. I recommend them.
