The EIO system uses a silicone shell which is made to fit over standard sized mason jars for an easy-to-grip surface. This is perfect for allowing little ones to drink from glass cups without worry about it slipping out of their hands. The sleeves are dishwasher safe, resist bacteria, and come in many fun, vibrant colors.
Parents can pair this sleeve with a special screw-on cap that fits over the top of the canning jars to protect against spills. The slow-flow top also reduces overpouring of drinks and reduces the amount that may come out if the cup spills over on the kitchen table. No spouts or valves are used with this product, which allows the child to learn how to properly sip from a cup to help transition them later to topless drink ware.
If you’re ready to find a way to responsibly reuse old mason jars, it’s time to strongly consider the EIO cup system!
