I bought a tall laundry basket with a lid because my room had a closet with beads instead of a door but Micki would pull the underwear out from the holes and Jack would just open the lid. Since then I've moved into a different room with a closet door. I even forget to close it most of the times but it seems they have pretty much grown out of their underwear stealing days...thankfully.

We had to also buy trash cans with the lids becasue they're all a bunch of trash stealers...but Jack figured out how to step on the lever and open it
