@spiralingside Can I stack 5 of them in 4" more than the height of 1? If not, then they don’t meet my strict definition of “stackable.” Plastic is thinner so they stack more tightly. I have glass containers, but they don’t really stack (nest), more just sit on top of each other. A 4" deep round glass container stacked on top of each other takes up about 7.5" of space, which is just a silly definition of stackable. Hell, blocks are stackable. I guess I mean nestable in a way that makes storage efficient and not stupid.
