DII Collapsible Polyester Storage Cube

I bought these because I liked that they had multiple design options. I was filling our storage cube shelf and didn't want all the same bins. So, they are perfect for that. However, they are not at all sturdy or durable. My kids are 11 and 14 so they aren't toddlers terrorizing things anymore and I'm still not sure how long we'll be able to make these work. In addition to being flimsy, they also discolored our white shelf. I noticed the other day that the navy seems to be coming off on the bottom of the shelf. I assume it's from sliding the bins in and out? In any case, while they are cute, I don't really think they're worth it. I've had more durable bins from Walmart.
