Ion8 OneTouch bottles have three different seals that keep them leakproof. In time, seals can get worn or damaged. Rather than throw away the whole bottle, we have made seals removable and replaceable, so you can extend the life of your bottle, and reduce waste.
If any of these parts are compromised or damaged such that they no longer form a seal, your bottle may leak. We do not think seals should need replaced for quite some time, even a number of years.
Seals are made of clear hypoallergenic food grade silicon.
(They are highlighted below in red)
Always make sure your seals are in good order!
If you need replacements, you can get them here.
