HOW TO MAKE THE COMPRESSION HAPPEN? There is an extra zipper outside of our compression packing cubes which can be zipped up to flatten the cubes and save space as far as possible. It works just like a vacuum sealer. (1) Fold your clothes and quilt, and flatten them. (2) Pack clothes in the cubes and zip the normal zipper. (3) Put a finger on the back of the zipper in the space when compressing the packing cubes in case the zipper get stuck in fabric. Declutter & Save Space Perfect for storing and organizing winter blankets, duvets, king and queen size comforters, sweaters, quilts, sheets, baby items etc. Hassle-free no-vacuum storage that has a big capacity though still compact.
