My husband bought two sets of these and organized all his tools and wood working supplies. They fit well together, are just the right fit for the average garage steel cabinets on wheels sold most anywhere. Keeps things in their own bin and has even given us extra space now! Would recommend these over the ones in the big box stores because of the texture on the bottom inside. The dots help keep things from moving inside the bin in the sliding drawers. As well it all holds solid to drawer bottoms. They lock into each other so they become one unit and they do not slide all over the drawer. How we did it, the drawers have extra room just enough to put that extra one thing, the ones that are your go to like an extra heavy duty scissors I reach for when dealing with package wraps and boxes. I told my husband I wish these were made for my kitchen!! Would be awesome to have! I hope the company would think about that one! Yes, we bought some of the available things for kitchen drawers and even rubber underneath those. And those dots you buy? Forget it! Guess what? The silverware tray still goes back in the drawer when you closet it! Get these we recommend.
