What can I do with a SD card?

Edit: I replaced it with a book

I'm specifically referring to microSD cards here, but I'm too lazy to type that every time and I doubt many people will think of full-sized ones anyway.

I got two 256GB SD cards (Samsung pro plus something) for Christmas, but I can't think of a good use for the second one.I have a Raspberry Pi, currently with a 32 GB SD card, where I'm gonna put the first one.My phone has 128 GB of storage, which is already enough for me.I'm considering putting it in my Nintendo Switch, but it already has a 64GB SD card, which is enough for the 2 non-physical games we have.I plan on getting a Steam Deck once I can afford it, but that already has a lot of storage.I don't have a camera or drone or similar.Selling is not an option.A refund is technically an option, but I'd rather find a use for it.
