With easy-clean lids and classic， space-saving shapes， this OXO Steel POP Container Set is just what you need for smart kitchen storage. Airtight seals help keep pantry staples and dry foods fresh. Yet each canister is a snap to open; simply push down on the button and it "pops" up. Lids come apart for thorough cleaning. Clear body construction includes a fill line so you can check supplies at a glance. Completely modular and stackable， these space-efficient containers can be configured to fit any size countertop， pantry and beyond.
<>br>Note: We recommend using the push-button to seal and unseal your POP Containers to ensure an airtight seal. The patented lid design features a silicone gasket with a flexible "fin." When you push the button， the gasket expands， pushing the fin against the POP Container walls to create an airtight barrier.Being able to pull the lid off without using the push-button does not mean the lid wasn't sealed. Pulling the lid off temporarily "breaks" the contact between the flexible silicone seal around the lid and the Container walls - allowing air to come in and the lid to come off.
