Our cupcake display risers are made of high quality acrylic with metal legs,each leg has two rubber rings to prevent the metal legs from scratching the acrylic board. We found the most 3 tier display stands are 2.7mm thick that will be cracked easily during shipment, so we decide to thicken our acrylic plate to 3mm. This is sturdy enough to hold your little heavy stones and minerals. Perfect for display cupcakes, nail polishes, Funko Pop, Nendoroids, Gundams, Tamashii and LEGOs! Display your assortment of products neatly. Our 3 tier acrylic half moon display stands can be used for multiple uses, nice way to showcase cupcakes, desserts, garage kits, perfume bottles, lipsticks, tabletop collectibles,small stones, minerals, crystals.
