This measuring glass is made of thick glass and feels very sturdy. The measurements are easy to read and in different units. I use this when measuring fertilizers and dechlorinators.
The shot glass is made of thick glass, so it is very durable and has some good weight on it as well. The printing on the sides to show volume is very good quality and I suspect it will last a very long time - no fading, peeling or chipping. Such a simple product, but so useful.
Great to use to measure anything for the aquarium. I use it mostly to dose water conditioner and meds when the cap to the bottle doesn't suit my needs ( if it even has one).
I am very happy with my little measuring cup, mostly because it has Aquarium CoOp printed on it and I can measure small amounts with it.
Works great for what it is supposed to do. Very legible writing on glass. Can quickly convert teaspoons, tblspoon, ml, ounces.
Works very well as a shot glass for gin and other adult grade drinks as well.
It is glass.
One might want to order 2 if using one for shot glass.
