Fits standard drink sizes up to 6-ouncesor177.441 ml if you wanna get specific.
"Reverse Force" lid is just a fancy way to say we engineered a very coollid that actually stays on,we know, it stays on #amensister!
Made of Borosilicate Glass which is said to belighterandstrongerthan ordinary glass but that doesn't mean they won't break, our cups are made of glass so you need to treat them like glass.
Thesilicone base comes all the way up the sides on this cup to meet the silicone lid making the cup fully enclosed sono glass is exposed.
Fully enclosed silicone base makes it non-slip, good-lookingand super comfortable to carry however please note that if you're a straight Long Black or Tea drinker you will find the cup hot to carry initially
