I purchased these to hold jewelry in the top two drawers of a small chest.  They work perfectly.  They hold 16 pairs of earrings or a combination of earrings and necklaces.  Some necklaces require two slots.  The best feature is the trays are sturdy enough to stack and slide to expose tray below.  They can even be picked up full of jewelry.  I wish they were available in black!!  Good, economical solution for storing lots of jewelry!
