I once threw away a water container I loved because the gasket was just impossible to clean. These look so fresh and have stayed clean, but I know I'll eventually not be able to clean them well and can just go to the next one that's in the multipack. Review: Perfect fit for my water bottles - I add electrolytes and flavor to my water bottle which does, even with regular cleaning, shorten the life of the gasket. These gaskets fit perfectly in my ThermoFlask and are very easy to install. ## Features - PERFECT COMPATIBILITY: Our replacement gaskets are fit perfectly with ThermoFlask water bottle with straw lid in both 16oz 24oz 32oz and 40oz sizes.
