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.
- 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 sizes and displays approximate volume markings in both ounces and milliliters
- Helps children and parents grip the bottle
- Made in the USA
