KOFFI ® KUP - Double Walled Glasses 400ml (10.5oz) - Borosilicate Glass - For Tea, Coffee, Latte, Cappuccino, Beer

These cups look beautiful and are great for both hot and cold drinks, they insulate very well - a fresh cup of coffee translates to a gentle warmth on the outside walls. They make for a stylish gift!I've dropped a star on these for two (minor) reasons. Firstly, the glasses are exceedingly light - it is quite surprising when you first unpackage them! They subsequently feel very delicate, and I'm unsure how well they would hold up if knocked. It was quite nerve wracking using these with an aeropress for the first time - I almost expected them to shatter beneath the force - but they have stood up to multiple uses so far. The second issue is that, despite being well packaged, one of the glasses had some very faint scratches/scuffs on the outside. They are barely noticeable, less so when full, so I wouldn't hold this against them.Overall would recommend, especially for the price!

Been using for 4 months now. Yes they are quite delicate but they are amazing and no problems with smashing as of yet or and ingress of fluid between the two layers. It's crazy how long the drink stays warm in this! 40 mins later my tea is still just above luke warm and drinkable, with nothing coving the top, great for someone who has a milly tea to help keep it hot or if you're like me and make a tea and then get busy and foget and come back to it! No need to keep sticking it in the microwave for re-heating :) The glass also does not get hot to hold on the outside because of the double insulation, even with a fresh boiling brew. Would definitely recommend getting some. Also cup is of a good size still! I was worried it wouldn't be enough for me as I like a big mug usually but is a perfect size cup.

When these arrived I thought I''d break them just getting them out of the packaging. They are made of extremely thin and fragile looking glass, remember test tubes in your school days Chemistry lessons? These are the same stuff.In practice though looks can be deceiving, they are extremely tough, very easy to clean, they look brilliant, lovely shaped design, easy to hold either by the handle or just holding the cup which due to the double wall never gets more than slightly warm. Most importantly though they keep your drink piping hot.

Nice glasses. They were bigger than expected - I thought they looked a bit crude/ clumsy at first but am now very happy with them.They are NOT microwaveable - according to the seller.

These are really nice cups and are slightly bigger than I imagined but keep the drink nice and warm until the end. The downside was I had one crack after just a few days. Now the seller replaced this one with 2 new ones which was great service, although after a couple of weeks a 2nd one cracked.

I was surprised how lightweight these cups are. That is no bad thing but I tend to handle with kid gloves because of the thiness of the glass. They remind me of those trick brandy glasses from joke shops. They look good though and no problems so far.

I've been looking for double walled glass mugs for a while, but couldn't find any that I found aesthetically pleasing... until I found these. The handles are a perfect size and shape, the size of the cup itself is just right and I love the way they look when they're full. Safe to say I'm very happy with them! They came well packed, and they're not as fragile as you might think.

Great glasses for our Nepresso coffee with hot milk heated in the microwave oven before hand. Looks great in these glasses , safe to touch and hold. Coffee tastes good too, it stays hot longer than usual in these glasses .Very satisfied with this company's customer service, personal with fast response in delivering and arriving in perfect condition.Very happy to recommend this company to anyone.
