Review on 🥃 Premium Double Wall Glass Cups - 8.5oz: For Ultimate Temperature Control and Elegant Sipping Experience by Josh Jeffries

As other reviews have said, water seeps into a hole in the floor and it's almost impossible to get out. When I got them from Revain and took them out of the box I wanted to wash them. I saw here that they can't be washed in the dishwasher - Ugh! So I put them in a sink filled with soapy water and hand washed them. And some of the walls got soapy water. I have no idea how to find out? Maybe dry in a low oven? But still I suspect that the soap leaves a discoloration in the glass. They look and feel good in your clothes but are actually poorly designed.
