I bought some of these in preparation for a big move thinking they'd be good for helping me conserve space. HA! What a joke. These bags give instructions for how to fill them up which I did, with sweaters and tshirts, etc. SOFT things that should have been easy cake for the Spacebag . Well when I went to zip the darn thing up the seam along the top next to the zipper BROKE because these are made from such CHEAP shoddy plastic material. I took them all back to the store for a full refund. What a waste!What a rip off!
