MB Cap MB Square

The silicone cap is positioned on the lid of the MB Original prior to the 2017 collection (not suitable for the MB Original Made in France) and the MB Square's lid to create a watertight and microwave-safe seal.

Simply lift them to open the containers to release steam and pressure that build up during heating, then press to close.

They’re available in a variety of colors, so you can also use them to customize your bentos!
