Bulavkus USB Flash Drive 

A memory stick in the form of a safety pin:

Bulavkus—a USB flash drive disguised as a classic safety pin—keeps your data safely pinned.
For finding Bulavkus in a flash, simply fasten to any fabric material and spare yourself frustration of digging through pockets.
Wear your data proudly.
