8oz Silicone Sleeve (1-Pack) - Regular Mouth Sleeve - Non-Toxic, Dishwasher Safe for Extra Grip & Protection - Made in USA (Jar NOT Included)

I bought for an OXO coffee creamer jar that has a very smooth exterior so slips easily but didn't work for me. It comes with a powder inside the sleeve that once cleaned off, doesn't allow for easy insertion of the jar.I have no interest in having something I can't clean regularly that can't be easily placed back on the jar. This is the only reason I returned it. Otherwise, it seemed well made, and liked the color (Aqua).

the shape doesn't necessarily fit all 8oz mason jars! AND there are NO RETURNS available so I wouldn't recommend buying this online (and I am a millennial online shopper) Rather than waste your money, purchase these in-store.tldr: NO RETURNS, NOT WORTH IT DON'T BUY

We just started using this, so not sure how it holds up to rough handling. I bought it and put it on a jar I already had bought for making jam and it fit perfectly. I would really like to get some of the other attachments, like the straws.

It's challenging to get the silicone on and off the glass jar. Not sure how it could be improved. Otherwise it's thick and fits 6oz jars perfectly.

These are good for anti slip but what I didn’t like about them is the measurement on the side is inaccurate unless you get the sleeve on just right which I can work around, it’s just a little inconvenient at times.

So far this has worked for us. We use the small jam jars and are using it for our toddler as a "first big cup". In order to protect the glass around the rim from a fall, I screw on the metal band for canning. I wish there was a better option for this.

This is thinner than I expected but works just fine. It slips on and off easily and is easy to clean. A good fit for my 1yr old so far.

Its perfect. Baby holds it like a champ.
