Instructions: 

1)  Simply pull out your antenna.
2)  Secure lobster clasp around the small end of your antenna
3)  Put your antenna back down.
4)  Custom made charms by request (just leave a comment for me)
 
Note: If you don't have an antenna, you can also clip the clasp to any cell phone case hole.

Note:  If you want a zipper pull  instead of the tiny lobster clasp, please make a note of it in the comment section...
