TO USE: Attach the post back (if there is one), leaving a small space on the post. Place the back through the keyhole and slide down into the slot. It"s that easy! If there is no post back, just hang them. Basically, it is best to put your longest earrings on the bottom and the smallest ones to fill in. Long dangles, chandelier & hoop earrings go on the bottom row of round holes or the bottom row of keyholes. * Currently the stock of Satin Nickel Silver still has the center l with a steel ball, but the Rubbed Bronze and the Black only have the center steel ball (2014 revision). It"s the capacity, quality and trouble-free design that sets this fabulous multi-purpose earring holder and jewelry organizer apart from the rest. Search ALL DEPARTMENTS for Angelynn"s Jewelry Organizers to see our entire collection of high quality jewelry organizers that are available in different styles and finishes matching most any decor. * EARRING CAPACITY & STORAGE: Beautifully displays 48 pairs of pierced earrings (if all of your earrings measure **2" long x 1" wide) at least 48 pair will easily fit; keeping them all up & out of harm"s way, beautifully displayed, seen at a glance and tangle free. Making it very simple to see and choose what you want to wear. There is 2 1/2" of clearance between the wall and the front of the organizer and there is also 4 1/2" of clearance between the accessory tray and the bottom row of round holes, which also means they work great for dangle earrings up to 4 1/2" long. * NECKLACE CAPACITY & STORAGE: Holds 25 to 50+ necklaces (1 to 2 necklaces per hook, depending upon your own jewelry collection style and size). The necklace hooks are heavy duty and well designed. They are flat-necklace-hooks that are very well spaced and staggered up-and-down, in-and-out which makes it very simple to see and choose what you want to wear and there is no need to unlatch your necklaces to remove them, truly trouble free. The length of necklaces is not limited since this item is wall mounted. There is approximately 1 1/4" of clearance between each hook so that they do not interfere with one another causing a problem instead of a solution. * To insure the authenticity of this product buy directly from Seller listed as "Angelynn"s Jewelry Organizers".
