Science of Coffee Mug

We looooved these mugs, unfortunately we have managed to accidentally break both of them. :( (Our fault, not the fault of the product. Gravity and all that.) They were great fun and if I thought we could avoid breaking a new set too, then I'd order them again. We miss them. We used them heavily and the etching always looked brand new, no damage from being washed.

This is the second item I have purchased from this company, both are amazing! I did see some concerning comments about the walls being thin. I am here to tell you that is total BS! Obviously it's not as thick as a full-blown ceramic coffee mug, but it's a good durable glass mug. Good s***

Very cute! Surprisingly lightweight but didn’t feel super fragile. My friend loved them.

The design is perfect for us science lovers. It's glass, so treat it with appropriate caution regarding hot liquids and handling with care to avoid breaking! Holds a wonderfully large amount of coffee for those difficult wake up days.

I've been searching for new glass coffee cups, and these were the first ones I found that called themselves durable. I LOVE these coffee cups!! They're lightweight, beautifully designed and perfect for my morning coffee. I highly recommend these beautiful cups to EVERYONE!!

We're heavier than expected and glass felt thicker. A little expensive for two.... roughly 12dollars a cup is alot. But they look cool and my fiance liked that they have science behind the straight glass look. Overall happy. 4stars because of price being a touch high.

A microwaveable mug I can use without the handle searing the skin off my fingers! I like the larger handle that arches away from the mug body and also appreciate the thinner glass; my beverage stays at a higher temp while sitting on the mug warmer (vobaga model vob 10 on the high setting gets very hot!). In fact, as the volume in the cup goes down, I must turn down the temp on the mug warmer (I know…duh!) Greenline is serious about the packaging for these mugs! This set of two mugs arrived in perfect condition securely nested in what appears to be custom molded foam and in a lovely ready-to-gift-wrap box (I know nothing about the magic of commercial packaging). I enjoy the sand etched designs; won’t wash off…yay, I get to enjoy the caffeine molecule designs for the life of the mug! This is all good news for me and I will add to the collection from Greenline Goods!

The Glass is Very Nice, rounded and smooth. We wondered if it was like lab glass and could be heated with a Bunsen burner? Not sure on That! Very Nice Coffee Mugs!

Excelente producto cumplió mis expectativas

Just bought another 2, very pleased with them. Excellent quality, well worth the price

Es demasiado cara aunque parece de calidad

Belles tasses, idéal pour cadeau, mais un peu grosse pour un café, convient plus pour des tisanes ou infusion

Am in love with the mug ♥️ If you are coffee mugs addicted you will like it .. ☕️
