WARNING: hollowing out cork is dangerous is knife cuts through cork. Some hot glue guns may be too hot and could damage your USB memory. I'm not responsible for any damages (to you or your USB).
This is for the Pocket Sized Comp(It's my first instructable ever).
Step 1: Find materials
Cork (the larger the better [Champagne cork even better])
USB (Buy only insides or open yourself)
Hot glue gun
Pocket Knife/Stanley Knife (preferably small blade)
Permanent marker or felt tip pen
