I found this case at a thrift store for like 80 cents. Figured I could use it for something someday, and alas! It has found its use. So I made it into this nifty little yoyo case. Thrift stores are the best.
thats awesome. Very steampunk ;D
Originally I think it was for cassette tapes. Anyone know what type of dye to use for the foam?
Looks just like samads.
black rit dye 
Any color RIT works… I like orange. Also I had that tape case in grade school, well maybe not that…
