I seem to have one junk drawer in every room. Main junk drawer in the media room has batteries, keys that I think I know what they open and don't want to toss. Walkie talkies, small flashlight and a tape measure. Old gift cards and maybe some old greeting cards that I wanted to keep and old cell phones.
Bedroom has batteries for TV remote, back scratcher, eye mask, reading glasses, Vick's, tissues, USB cables.
Kitchen has packaged plastic cutlery that I pick up from take-out foods. Wrapped straws, old measuring spoons, old cookie cutters, individual packaged salt and black pepper packs.
Office has USB cables, mail that I have meant to open, cough drops, reading glasses, more batteries, old USB sticks, back scratchers, souvenir key rings. Keys that I have no idea what they open.
