I was beyond thrilled when I found these baskets because they were exactly what I was envisioning when styling the bookshelves! They are sturdy and hold a decent amount of stuff. One basket I have dedicated to all my kid's wooden puzzles, and not only do they fit, but I have them arranged on a metal puzzle organizer, and it all fits in the basket! I love how it is lined with a white cloth that can be tied up to cover up anything inside the basket.
