What do you do with your spare parts?

[(OO)SKYLINE(OO)]

I usually leave them in the box.

But when the boxes start piling up, I put them in a draw which I have and dispose the boxes.

I store them in ziploc bags and then in a set of boxes.

I store them in a Ziploc bag then put them in a small dresser in my room.
I don't have the space to keep all my boxes so I keep the cool boxes and toss the rest.
I enjoy watching the garbage men looking at the boxes trying to figure out what they're for LOL!
