Review on 🔹 MyGift Wall Mounted Clear Acrylic Collectible Display Case: Showcase Your Mini Toys, Crystals, and Stones in Style with 12 Compartments by Adrienne Holmes

It's open on both the front and back so be careful if you plan on leaning something against your back - it won't work. It also has angled hanging holes on the back to hang it horizontally but not vertically. Installing on a flat surface worked for me. I bought two of these to display some of my rock, fossil and mineral collections. You are perfect. I also bought some clear acrylic coasters that go great with the clear acrylic organizers. Not only are these shelves great for displaying rocks and minerals, but also shells, paperweights, small snow globes, music boxes, etc. and all small collectibles.
