As seen in the photo above, the "twin bar" feature on this Jewelry Display Case is designed to hold and display your post or stud earrings.  While most of the Solid Stainless Steel resting bars on our Jewelry Display Case will hold  fish hook, lever back, clip-on, kidney wires, hoops and similar earrings, this organizer has devoted rows 5 and 6 to the specific task of displaying your lovely post and stud earrings.  These 2 rows will allow you plenty of room to store your favorite post or stud earrings. If your collection of jewelry has  less post earring types, then you do have the option of using the twin bar feature to hold your earrings in the same manner as the single Solid Stainless Steel Bars in this Jewelry Display Case.  The goal of our Jewelry Display Case is to provide you with place to properly organize and show all your various treasures in one beautiful location, and the twin bar system helps to complete this goal.
