This stackable shoe storage case features a sturdy double-frame foldable structure for easy assembly without complicated tools, made of eco-friendly PP and high-impact polystyrene (HIPS) material for toughness and transparency. Each large-sized box measures 33×23×14cm, spacious enough to hold sneakers, casual shoes, flats and low-top boots. Equipped with a black full-frame pull front door and circular handle cutout, the transparent panel lets you quickly spot shoes inside while blocking dust and moisture. The interlocking edge design allows stable vertical stacking to build multi-layer shoe racks, perfect for entryways, bedrooms and closets. Sold in a set of 12 boxes, this foldable design can be flattened for compact storage when not in use, bringing neat shoe organization to small living spaces.
