Clear lidded boxes for storage/display. (Penzance TR18)

I have 3 large, sturdy (empty!) Hotel Chocolate boxes, 47 x 24 x 6.5 cm. They have a large viewing window in the lid so may convert to dust-free display for Lego figures or storage of wools/other craft materials. Could anyone make use of them? (Book in photo to give idea of size.)
