Great product
Item Package Quantity: 1, Size: 2 Tiers 24 Inch, Item Package Quantity: 1, Size: 2 Tiers 24 Inch
Great item. I love the look, it’s perfect for displaying my collection. I didn’t actually set it up per the instructions, I modified it, but it’s like legos, you can get creative. I only attached the top and they hang. Use better fasteners though, I don’t trust the ones they provide

These are perfect!

These were a great purchase! I bought two of them, and they look great in my son’s room, as he likes to collect and display action figures. The wood shelves and metal bars are of good quality and are also the perfect size and height. Also excellent value for the price!

Nice shelves that will work with some modifications
Item Package Quantity: 1, Size: 6 Tiers, Item Package Quantity: 1, Size: 6 Tiers
Pay attention to the bottom shelf and where it is relative to the floor. It’s only about 6 inches, which isn’t good for a retail environment. I swapped the bottom nipples out for some 10” nipples and the results were night and day. So much better now.
