I've tried a lot of methods for organizing my jewelry and this one works the best for me, though it isn't perfect. On the plus side, its internal dividers are tarnish-resistant. The containers come in a wide variety of divisions, from three to thirty-six, and two sizes. All of them stack, and they have a thin plastic cover to protect the contents. On the minus side, the covers slide right off and don't seal. They simply lie on the containers. Also, if you have a LOT of jewelry, as I do, it can be a nuisance to lift one container after another after another to find what you want. But since you can keep buying and stacking the modules, it outperforms a jewelry box (too small) and an acrylic holder (too large a footprint) and the popular hanging pockets (too awkward). One improvement I'd like to see: I have necklace and earring sets and there's no Neatnix organizer designed with a larger compartment for the necklace and a smaller one for the earrings. If they created one like that, I'd be first on line to buy it. Also, a cover that seals would be great.
