The tab checks are patented one way valves that work with the Pump N’ Seal® and Flav-O-Nator®. Tab Checks® must be used on any can or jar that you are using as a storage container. Tab Checks® allow the Pump N’ Seal® unit to draw out the air that spoils food out of the container while locking freshness in. NO CANADIAN ORDERS PLEASE.
