What's a useless item you own?

[Ja sa bong]

Do you have any useless item which you own that's still in your possession but for some reason you can't get rid of it?

I'm still in possession of my dad's vinyl records which I don't think are worth much but I can't get rid of them.

Do you still have any items deemed useless but you can't dispose them?

I have a digimon vital bracelet but thanks to bandai the app doesn't work making it kind of useless but it cost me $60 so I can't just throw it away.
