in a padded envelope and put 99 cents postage on it (three stamps). it is a good idea to use delivery confirmation. if you send the pen in a small priority mail box, delivery confirmation is included.
if you have broken your pocket clip, you have to mail the pen to me for replacement. if the clip is loose, then tap the top on something solid like a wood table, and the clip will tighten.
this usually happens if you turn the pen top too far to the right. turn the top left (unscrew counter-clockwise) to open the pen. if the mechanism is stripped, you will have to mail it to me
