What do you do with the expensive or genuinely useful gifts your ex gave you after a breakup?

I get throwing away the hoodie, donating it, or even letting your next partner steal it. Letters can be burned or tossed. That part makes sense.

But what about the gifts that are actually expensive, useful, or just too cool to get rid of?
Things like a PS5, a Dyson, an astronaut lamp, a LEGO set, a designer handbag, or something you genuinely use every day.

Do you keep using them without thinking about it, sell them, return them, pack them away, or get rid of them because of the memories?
