How do I use GladWare® Containers with Interlocking Lids?
Locking lids together is easy — just place one lid on a flat surface and a second lid of the same shape on top. Gently press down on the button in the center of the top lid until you feel the two lids connect. You can repeat this process to lock additional lids of the same shape onto the stack. Once you have locked lids together, store the stack of connected lids in your container storage area. Your lids will stay organized and the right lid will be there when you need it.
