They are numbered and 'color-coded' aka you get 2 red and 2 grey. For organization! Because obviously if you have trouble remembering what you put in each cube, sewing a tag that says 1 on it will solve all of your problems! lol. I do get that this would be helpful to some, and some may even make a master list to refer to or something. But... you could just... do that yourself... Anyways, they were pretty much the same size as the slim cubes from Ebags, which currently you can get a 3 pack for $20.29. These ones were 4 for $35 or $40. It's expensive to be organized!
