Sleeve protects bottle from breaking and I’m guessing for letting the little ones get hurt! They’re online for $6. The design is really cute! They should make more colors! I highly recommend this with the bottles!

This works well to protect the glass, but is hard to remove and put on due to the bottle shape. One bottle fell off the counter and didn’t crack, so I would say it’s worth it. I like the cutout widow so the measurements are visible with the sleeve on.
