Grooves on the lid are designed to stack multiple storage bins securely to maximize limited storage space and create a customized storage solution. Stacking grooves also allow boxes to lock in place and prevent shifting or sliding when stacked. The element-resistant seal helps protect contents from moisture, dust, and pests. Heavy-duty buckle latches keep the lids secure.
