Thanks guys. I bought an extra pocket knife in case I can't think of anything, but I'm liking the dice box idea. I know this wasn't made for gaming, but I'm loving it: http://www.etsy.com/listing/74240021/padauk-jewelrykeepsake-box-tmp20110035
It would be so perfect. It's all gorgeous, and it even has a little tray! Wish it didn't cost $150.
I emailed a company that makes metal dice to ask if they had any blanks, but they said no. That would've been sweeeeeeet!
