What do you secretly hoard?

I try my hardest to keep my apartment neat (coming from parents that had hoarding tendencies) but there are some things I just cannot help but collect. In no particular order --

-Rocks/seashells from vacations

-Spices (who really needs THAT MANY SPICE BLENDS?? Why do I never have the one I need??)

-Mini lipsticks and sample face products. (I have SO MANY of these from when I subscribed to Birchbox that I've barely even used! Yet I can't throw them away.

- Old hair dyes (Maybe I will want that Manic Panic Atomic Turquoise hair dye one day!)

- Cables. Never seen a cable I could throw away!

Please tell me I'm not alone!! What do you hoard?
