Very nice!
The original straw is too small, so the seller sent extra in the right size! Thank you for making it right for us 👍

Very thin and non durable. 2 came broken
They are very thin and 2 came broken. The ones that are good won't last long. The straws look nice and the lids are not spilling, the size and shape is good.

Fragile
They’re very cute but very fragile. Also when they arrived I found the 2 of the glass straw broken

Won't etch with cream
Ok so the glasses are a decent size and thickness, the lids seal well, and no issues with straws. So why 3 stars? They will not etch with etching cream. The sole reason i bought them, and it doesn't work. Ive applied the cream in a thicker than normal layer and left it on for much longer than normal... it washes right off as if it was never even applied. Annoying but not to the level of submitting a return. I can use them for other projects, but just a warning to fellow etch cream users. High chance it won't work, buy at your own risk.
