I bought a five-drawer desk organizer a while back to keep things like that in. Stands go in one drawer, weapons and general accessories in another, Figma bags in the third, and I keep Figuarts hands and small accessories (like cards) in individual bags in a fourth drawer.

I keep my stuff like hands and weapons in the box. However I'm running out of room to put my boxes since I only have one shelve for my figuarts and my other figures.

Quart size Ziplock bag.

I keep them in the box but man I ran out of room for the boxes, I had a drawer dedicated to them that filled up, but I do keep a lot of things that I need to get rid of.

keep in box.

I have a small zip lock bag for each figuart for the hands and accessories. That way I can see what I want and quickly grab it. I store all those bags in a big tub with a locking lid. I have no need for boxes, I actually need to throw all mine away in the morning.

Keep them in the box, and put the pile of boxes next to a shelf.

For MonsterArts and effect sets, I have a combinable set of containers I keep them in.

FOr Figuarts, I keep their accessories in their specific boxes. I just can not justify throwing out the boxes for various reasons.

I never like throwing away my boxes. I do put some back in their boxes when I run out of room for stuff.

I actually just did that with my entire Shinkenger collection. Although, I might just try to sell them off. Of course, I haven't had any luck with getting rid of my Boukengers...
