Flip top containers (Chirk Bank LL14)

I have four flip top containers. These have been used to store 3d printing filament and had holes drilled into them for the filament to pass through. Other than the holes these are in very good condition. Each one measures 6" x 8" and 12" high. They could have multiple uses but one that springs to mind is to store Lego bricks. Ideally go as a set of 4.
