Well...you could buy one, but the ones I found worth buying were pretty expensive. Now, you can find some handmade ones on ebaY that won't set you back so far, but they're not made in any medieval manner, they're wooden boxes with hinges and such but you can stain'm if you are so inclined and they'll have the look w/out the expense. You can do a search for 'wooden storage box' on ebaY to see what I mean.
I have an antique chest I use for now, but am thinking of taking everything out because its so old and I don't want to damage it. Some of the wood is starting to split along the grain.
