At 4.9" deep, the sturdy LEGO ZipBin 500 Brick Storage Brick is a neat way to play with and store LEGO bricks, figures and other toys. The box unzips into a flat, wipe-clean build-and-play surface. Every item is accessible - from the smallest to the largest, including the ones at the bottom of the bin - with no dumping, no mess; kids can easily find exactly what they want. When playtime is over, the mat zips back up to effortlessly store the entire toy collection inside. It's an easily portable, completely integrated toy case/play arena - no separate lid to worry about. Unobtrusive package design doesn't clash with most home decor. Toys sold separately. Like every Neat-Oh! product, the LEGO ZipBin 500 Brick Storage Bin is manufactured to the highest quality and safety standards. The company's comprehensive product testing program exceeds industry requirements. It tests for 19 heavy metals, not the mandated 8, it hand sews products, and it uses self-repairing zippers and food-grade inks. They're products you can believe in.
