"I like to mix smoothies in my 32 oz mason jars because it’s fast with minimal clean up using an immersion blender but I have small hands and those jars get pretty slippery when they sweat. These sleeves completely solve that problem. I no longer feel like I am constantly about to drop my jar. They were easy to get on but seem like they will stay put. I knocked off one star because the pack of four colors showed peach and I got a boring grey sleeve instead which honestly bummed me out much more than it should have. I would definitely purchase these again."

If you use mason jars these are worth the money. They are made with good quality silicone, wash easily and will last with normal care. They protect your glassware during transporting and protect your hands from hot foods when storing soup or home canning. They are also very attractive, fit well and have a good grip, so would make a smart addition when serving drinks in mason jars.skee

I like these sleeves. They come packaged in a cloth mesh draw string bag which is nice to store the unused sleeves. They fit quite well on a quart size Ball Mason jar, not too tight to make it impossible to get it on but tight enough to keep it in place. One tip though; They are a bit greasy as delivered. Wash them throughly in dawn dish soap to clean off the leftover release agent from the molding process. After that, you are good to go. I paired them up with some drinking lids to make a good water bottle to keep at my desk. I would recommend these sleeves.eagle eye mike
