Vicenpal 16 Pieces Acrylic Square Display Blocks 3 x 3 x 1 Inches Clear Polished Acrylic Cube Jewelry Display Stand Ring Showcase Holder Base

If you’re looking for library & retail level displays you can buy the same items on Amazon & elsewhere. Buy multiple sizes of angled displays (mass market paperback, trade, & hardback) & be sure to pick up some cubes & squares for the inevitable tchotchkes too. Rearranging these are my go to when insomnia hits :)Book stands..Acrylic squares.
