Mason jars are made of extremely durable thick-walled glass that can survive most drops. If you want extra protection, and a better grip, add a Mason Bottle Silicone Sleeve to your jar.
Our silicone sleeves can be used well after baby finishes with bottle feeding. Use it on mason jars as a toddler training cup, snack container, or even for your morning coffee.
This product includes One Silicone Sleeve, available in 4 oz. or 8 oz. sizes.
- Fits regular-mouth mason jars in either the 4 oz. or 8 oz. sizes
- Shows the contents of the bottle through windows on both sides
- Displays approximate volume markings in both ounces and milliliters
- Helps children and parents grip the bottle
- 100% Made in the USA
