Convert a standard mason jar into a stylish sippy cup for your little one. Easy to clean and BPA free, the Mason Jar Sippy Cup is the perfect choice for beverages at home or on the go.

The Mason Jar Sippy Cup sleeve snugly fits a 250ML mason jar and features a safety strap across the bottom to keep the jar in place. The reinforced internal layer provides stability and protects tiny hands from beverage temperatures.

Mason Jar Sleeves are made from a combination of premium cotton and up-cycled textiles.


We use a dishwasher BPA-free recycled plastic lid* for our Mason Jar Sippy Cups. It’s strong, doesn’t hold stains, and is dishwasher safe. Add it to your order today.


This product is designed to be used with a 250 ML mason jar only! Please do not use any substitutions as contents may spill and cause injury with a different size.
