ComSaf 400ml Glass Coffee Mugs Set of 4, Clear Glass Coffee Cup with Big Handle, Large Borosilicate Glass Mug for Tea Milk or Hot Cold Beverages, Crystal Drinking Glass for Birthday

I have used these for a couple of months now and am really pleased. The glass is not thick, but they appear to be robust as I have bashed them on my porcelain sink multiple times while washing them - and there isn't even a chip.I chose glass mugs because I have wasted so many of my hot drinks by forgetting about them, being able to see the content is a good reminder. I also invested in a cup warmer to keep the drink hot - these mugs have a completely flat bottom so work perfectly on the warmer. The days of wasting drinks because I forgot and they went cold are over. My drink is still hot 2 hours later.My family have been impressed I have even purchased a set for them.

Love These! Made in fine borosiliicate glass which is a pleasure to drink from.40 ml capacity. This helps my Hubby and l monitor our liquid intake.Versatile for both hot and cold drinks, soups etc. Pleased to recommend this product and excellent Seller Service.

They are as described, seem sturdy as have been okay in the dishwasher. Good value for money. Would recommend.

Love the mugs but one of them the handle was really badly chipped

Love these coffee cups - light to hold and good to clean

Average quality - glass feels quite thin almost plastic. Functional but cheap feel.

Very good quality, large cups

The mugs were extremely well wrapped so no damage occurred during transit. They are exactly the same as the mugs used by Bear Cafes which is what I wanted. Love the feel and look of the mugs.
