16L Plastic Collapsible Storage Crates,Folding Crates Storage,Pack of 4,Black

Pleasantly surprised with these! Handy storage crates that easily fold down to take up less space when not in use. Easy to open, just lift up the long sides and the shorter sides drop into place. Just push the bottom corners to snap them into place. Stackable. I put one in my Jeep to keep junk in. One has all my my car wash stuff. One in my closet.But the main reason I bought them is I am using one on my rear bike rack. It’s nice that it folds down flat. So if I’m cycling with a lot of gear, trip to the store, or whatever I can open it up and pack it full. And folded flat I can bungie something simple to the top of it, like my jacket if I don’t want to ride around with a full size crate on the back.Plastic is strong. I drilled 4 holes in the bottom and bolted it to the bike rack. No worries about the plastic cracking. In the open position it stays open on its own fairly well. You need to push all the lower corners in for it to collapse down flat.Overall I am pleased. No complaints.
