Review on Case Of 6 Storex Small Book Bins, 11.75 X 4.5 X 8.5 Inches, Multicolor Classroom Assortment - Assorted Colors (Color Variations May Occur) by Pete Door

You get six for $4.69. So adjust your expectations. They are better quality than what you get at the dollar store or walmart (target might have better ones, but those will cost more) These are smaller than the typical book bin and do taper a lot. So waisted space can be an issue. They are perfect for those thin scholastic type books. I don't think these would hold up well in a classroom setting. They are made from a thinner plastic, but snap together well.
