LOL Sorry no it's in inches. .5 centimeters would be really hard to fill heheh
I read your first post as centimeters too, and thought "How many things did you get in there?" You would need a matchbox packing machine for that!
I've got your box mostly packed, though there's a bit of room left to fill. I've been blanking on how to decorate it, but suddenly got moving last night. It'll take a few days, though. Thelastkodama's box is finished and pretty much stuffed, though I can see lots of little gaps that can be filled with seed beads, tiny jewels, buttons, etc.
