Caffeine Beaker Mug 17 oz (500ml) with Metal Spoon - Chemistry Mug - Borosilicate Glass Coffee Mugs with Handle and Measuring for Coffee/Latte/Tea - Caffeine Molecule Cup - Science Coffee Mug

This mug is perfect for my morning coffee. Aesthetically pleasing as well as functional. A bit pricey but worth every penny.

The only slight disappointment is that it seems not to be borosilicate glass, but it is a high quality glass product anyway. I noticed that the scale is printed slightly too high on the cup to be accurate, but the +-5% graphic just below the 500ml line covers that, and made me smile!

Fun, although I would recommend enjoying COLD drinks only!

Lightest mugs I own and when I dropped it on the wood floor it bounced! Fantastic!

I had one these about 30 years ago and loved it then, not sure what happened to it, so after seeing this one I decided to purchase it since the glass t was probably thicker than the other ones I’ve seen. I only wish the handle was thicker/wider.

My wife got a glass similar to this as a gift, and it wasn't long, maybe a few weeks, before it was cracked and leaking. She was kind of heartbroken. So I went to the 'zon, did some research, looked for borosilicate glass, and this was one of the few that described 3mm thickness, which after looking at the old glass which seemed to be 2mm or less. This one has more heft and doesn't feel like the action of setting it down risks breakage. The spoon was a bonus. Very satisfied with this, don't waste your time with a cheaper version.

I got this as a gift, and it arrived very nicely packaged. My STEM student loved this and it was a hit at her birthday party. The glass is really thin, so it feels fragile. However, it has been in the microwave, in the dishwasher several times now, and it still looks new. This makes a great gift and I highly recommend it.

This cute product was a gift for my daughter's Chemistry teacher. It is a great product which come in a very nice box for gifting. It also Shipped pretty quickly as we were on a very tight deadline. My daughter loved it and hopefully her teacher does as well.
