"Purchased this so I could make large cups o’tea in a big mason jar! I purchased the teal. The cut outs and color are really fabulous and looks super cute. Took off one star because the sleeve is not quite thick enough to keep from burning your hands (even if you make sure not to grip where the cut outs are). Anyways, it’s super cute but not for hot liquids!"

It’s just perfect. My last water bottle broke and I use mason jars for everything so I thought I’d turn one into my new water bottle. I take my bottle EVERYWHERE, so the main reason I bought this was for grip and protection. An unexpected bonus was that I can use it as a travel mug for my coffee because the sleeve protected my hand from the heat which I was delightfully surprised about.It was quite easy to shimmy on which I did before I saw that they included instructions on how to put it on. I receive a lot of things from amazon that SHOULD have instructions but don’t, so I thought it was a nice touch.And best of all it’s cute. A lot of the other products I found covered up the jar too much and I wasn’t necessarily looking for insulation so this still shows off the cute mason jar that it is.So yeah. Love love love love love love love.jennie

Love it! It fits snuggly and is nice and thick to protect the glass. It's way easier to get on than the average silicone sleeve, and I love that the cutouts are small enough that it doesn't slide around.forestfam10

I bought this a couple of years ago. Use it everyday. It keeps me from dropping my glass jar. (I use it for drinking water throughout the day.). It also helps a little when the contents are too hot to holdWhat Customers Talk About
