Caffeine Molecule Beaker Novelty Mug - Molecule and Chemistry Joke on Front and Funny Scale on Back - Thoughtful Geek Science Friend Teacher Student Present - 13 ounces - With Gift Box

Arrived quickly and in FANTASTIC condition. My boyfriend is a biochem major and coffee lover. He went crazy over this mug. We have hand washed as well as on the top rack dishwasher. It has not chipped or faded. The glass is thick and sturdy and it holds heat well. My boyfriend also likes to leave spare coffee in a mug for a few days and the glass hasn't stained or developed a foul smell. It really was a cool gift worth the price.

i wanted to get this mug for my boyfriend but i liked it so much that i ordered 2, it came in a beautiful box that was just perfect for giving it as a gift. He enjoyed the funny message on the front quite a bit plus it has the correct lab beaker shape and it resisted the hot coffee high temp perfectly, works great!

The cup is pretty flimsy and more for decoration than everyday use. The design is very cute...I just wish they printed it on more sturdier glass.

Good, big mug. Received a lot of compliments on this cute mug. I use it all the time.

I bought this for the funny inscriptions on front and back. Description says "Dishwasher safe top quality print will last for years." It did not. The inscriptions slowly washed away until they were completely gone after months. So now it's just a plain thin cheap-looking glass mug. It's a great conversation piece - if you don't use it.

Love this.. Super cute. Seems nice and sturdy. Have washed and used several times.
