on here about how to mail chips in the mail. A very inexpensive way that I do it is by putting the item in a holder and taping it with REMOVABLE SCOTCH TAPE to a piece of cardboard I cut to fit a padded envelope. VERY inexpensive, fast and easy to do. Removable tape is available at any stationary store. It is in a blue box. I've been doing this for over 20 years now, and have not had a broken chip yet.
Just thought you'd like to know a different alternative that has worked for me.
