The latching lids snap shut securely, which is a relief since these bins are packed with heavy yarn and tools. They stack perfectly on my shelf without wobbling, and the 32-quart size holds more than I expected.
I was worried about stacking these in my closet, but the 18.5 by 15 inch footprint fits perfectly on my shelf and they lock together without wobbling. The 9-inch inner depth is just right for my yarn and fabric scraps, and the lids stay put even when I jam them full.
The latching lids actually snap shut tight, so my ribbon spools and fabric scraps don't spill when I stack three high in the closet. Inner depth is a true 9 inches, which fits my taller glue bottles standing up. Six of these cleared my whole craft shelf.
