The gasket seal actually works — I left one outside through two rainstorms and everything inside stayed bone dry. The clear sides are handy since I can see what's in each bin without pulling them off the stack.
I've been storing my winter blankets in these and the gasket seal really does keep the damp out of my garage. Stacking them two high hasn't caused any bowing in the lids either.
The clear lids are a game changer for my garage—I can spot the holiday decorations or camping gear instantly without unstacking anything. The gasket seal snapped shut with a satisfying click on all four boxes, and they’ve stayed dust-free through a dusty summer remodel.
