Does anyone have a hope chest?

I've started to collect items for my future child even though it'll be a few years down the road. Usually I get something when I can't stop thinking about it or I think it'll be gone when i have my babies. I also collect when I travel. I have infertility issues and this makes me feel better and it gives me true hope!

What do you store your items in? A literal chest, a box?

I'd love to purchase something to hold these special belongings as well as keep them protected through a move across country. I've looked everywhere and can't find anything appropriate.
