Suwimut 2 Pack Caffeine Beaker Mug, 16 oz Borosilicate Glass Caffeine Molecule Mug, Clear Chemistry Coffee Mugs with Handle and Measuring for Tea, Coffee, Latte, Hot and Cold Beverage

tl;dr: Excellent cup that has a metric measuring. Be careful of sweating & sticking if not using a coaster. This is great for the science-minded folk or even people who want a little "metric" measuring cup. At first I was concerned the glass was going to be delicate because it is somewhat thin and light. After a couple of clumsy bumps on the rim, handle, etc, it still holds up nice. The handle is big enough to hold comfortable if you have large hands (might not fit all fingers thru back thats okay). I really like the metric measuring on the side. 200 mL is ~6 oz, 375 mL = ~12 oz. So if you use the larger cup settings on Keurig or have a heavy pour, you should still have enough for decent amount of cream. I have used this both with cold brew and hot coffee. It works nicely for both but I do not think it is insulated. It also will sweat. Due to how the bottom is made, it may stick to the tabletop so use a coaster. There have been sometimes it sweats from cold brew, stuck to the table, and spilled as it became yanked. Overall I love it and I love that it was a two pack.

These seem like good quality glass mugs. My husband and oldest son are both scientists in real life (meteorology and biology researcher at MIT) and will appreciate the humor in them. The glass seems very sturdy and the markings are clear. I'll let you know after Fathers' Day and my sons' birthday (early July) how they liked them. Linneaann

I use this every day. LITERALLY, basically this is the first thing I grab in my kitchen for most stuff. Like boiling water in the microwave. measuring any liquids as well. Simple and straight to the point. It feel like a real chemistry utensil. looks great, not very heavy, feels great in your hands. good size. I would guess it is very durable, but dont drop it like I did and broke one. but I simply bought another set and I also gave it away as a gift.

After having these for a year I have changed my mind about them. They have held up very well and surprisingly keep my drinks cold. I give four stars because I needed to be convinced that they weren't as fragile as I first thought. Buy these with confidence. Original review below. I enjoy fun glassware. I liked the looks of the mugs, that's why I bought them. However, that's where everything I like about these mugs ends. The glass is really thin. It's thickness is approx. 3/32" of an inch (.094" if you're into decimals). Our cheap wine glasses are slightly thicker The handle is approx. 3/8" in diameter. The mug weighs 5.8 ounces, which is not much. They feel way too light for a mug. Sturdy is not a word I would use to describe these mugs even though they are said to be made of borosilicate glass. I would of expected them to be thicker. Maybe next time I'll buy actual laboratory glassware. I'm going to keep them to see how they hold up, but I'm not very confident about that.

Bought these for a coworker, high school chemistry teacher - who can say no to putting their coffee in a cute cup like that? They're great glasses, I believe they were dishwasher safe. Great size and I love that it came with two cups! Definitely worth the price range, it's a great gift idea!

Came in the mail quickly and look great. Perfect for the chemist or nerd in your life!

I purchased it for its clear markings -- I make high-precision coffee every day and need to measure the water, milk, etc., correctly. Alas, after a few washings in the dishwasher, the markings disappeared. The glass itself appears to be of very good quality. I still use it -- but can't measure! BTW, I have not checked if it is recommended to hand-wash. I wouldn't anyway!

Bought these "Suwimut 2 Pack Caffeine Beaker Mug" as a gift for my wife who is a Lab Tech! She loves them! They are used with an espresso machine, and they work great. The graphics on the cups are clear and crisp. I've heard that some people had issues with using these in dishwashers (washing away the graphics), so to be safe we have only been hand washing these cups. The glass looks quite thin, but so far seems sturdy enough.

Die Gläser an sich sind echt cool, keine Frage. Haben sie vor ca. 3-4 Monaten bestellt. Leider ist jetzt nach dieser Zeit der Druck bereits sehr blass geworden. Ich habe eines der Gläser von Hand gewaschen und das andere Parallel im Geschirrspüler. Bei beiden hat sich mittlerweile der Druck sehr verflüchtigt. Ich schätze das in ein paar Monaten kein Aufdruck mehr übrig sein wird. Die Gläser an sich sind ohne den Aufdruck leider recht witzlos. Auf lange Sicht bleibt hier die Freude aus. Keine Empfehlung meinerseits. Würde sie nicht noch einmal kaufen.

Great for coffee and science

This was a gift for two science teachers and they felt instantly in love with them. Definitely recommend them and they’re very fancy!!!!

Suspect it would break easily with normal use.

Les tasses sont belles d’une bonne grandeur, les signes de chimie de la caféine sont le fun pour mon petit club de chimiste
