What makes Clever Crates so smart is their fold-flat design, enabling you to close & store them flat, freeing up valuable closet & storage space when their contents come out. For decluttering & organizing the garage, summer camp, kid’s room or attic, these foldable, plastic multi-use crates are ideal, available in 46-liter & 25-liter “milk crate” styles that stack vertically when in use & collapse flat in seconds.
