NOTE: The compartments of each tray correspond exactly with the specially patterned silicone lid, which works to lock in moisture, preventing leaks, even between compartments.
Each Munchbox product MUST be used only with its correct inner tray, i.e. Munchbox Mini4 must be used with its corresponding four compartment tray, and Munchbox Maxi6 with the six compartment tray.
The patterns specific to each box and tray combination are what make it leakproof.
