These are nice quality glasses. This is a set of four, 8 ounce size, handcrafted glasses. They are made of borosilicate glass and have thick rims. They they feel lighter then what I expected. They are easy to grip on to because of how they are shaped.
They were extremely well packaged. Each one was wrapped in bubble wrap and inside the its package box and then in a shipping box.
They are double walled so they are insulated. Normally any glass I use would have condensation down the side and onto my table, but not with these. My drink is able to stay colder a lot longer then any other glass I own. These are safe to even use for hot beverages, although I have not tried them that way yet.
They are freezer, microwave, and dishwasher safe.
The company offers a 1 year warranty.
