I'm going to start this with my biggest collection aka my Reds collection.
I went to my first Reds game when I was 3, and I've been a fan ever since.

Duct tape (not pictured)
Mr. Red doll
And a home made blanket
My yo-yo's. Yes, I am that nerd that knows tons of tricks and always has a yo-yo (or 8) with them. (I even have a yo-yo holster, get on my level.)
Beginner yo-yo (clear)
Trick yo-yo (blue)
Clutch yo-yo's (green and orange)
Fixed axel yo-yo's (Frozen TMNT)
Broken clutch yo-to (captain America)
"Advanced" yo-yo (holographic)
This is a small portion of my HK stuff
I have way more different collections (doctor who stuff, nail supplies, some Kpop merch, etc), but these are some of my favorite things, and I feel like they kind of give some insight to who I am.
(I need to stop making such long posts!)
