Review on ☕ 4-Pack Neoprene Coffee Sleeves - Anti-Slip, 3mm Thick, Collapsible & Heat Resistant - Insulated Cup Sleeves for Coffee, Tea, and Cold Drinks - Red, Green, Light Blue, Purple by Alfreada Leotta

These cases are perfect for my glasses and water bottles! My containers are 9 1/8" around the top of the sleeves. They insulate containers from the cold and make them easy to lift. They also absorb some of the condensed moisture so there's less mess elsewhere. The reason for 4 stars instead of 5 is they smell something it's not very strong or offensive I washed them but it didn't remove the smell However the sleeves don't touch my drink and stay far enough from my nose for the smell to catch me doesn't bother me. I use them all day, every day as I always have a glass of ice water by my side. I would buy them again.
