4-Tier Black Stackable Foldable Storage Bins with Lid & Wheels

Customers generally find the product easy to assemble and appreciate its attractive appearance. The wheels are noted as a useful feature for mobility. However, opinions on sturdiness are mixed, with some finding it flimsy and not suitable for heavy items, while others consider it sturdy. The material is described as plastic, with some wishing it were thicker, and one review mentioned issues with cellophane getting caught in the frames.
