I needed a rolling cart with bins to store my gemstones and beads.Started storing my little plastic boxes of beads,tried to slide the plastic drawers,they gave way!!The plastic drawers are made"soft" and "weak". Any weight put in the drawers causes the side of the plastic drawers to"give-way" then they come off the metal tracks. You have to empty them completely to satisfactorily slide the drawers in and out. I have 10 of these units I have invested $$$ in.Would NOT recommend them to ANYONE!!
