U.S.P.S. can mess up your stuff even if you pack and mail properly. This package was sent to me by a VERY NICE person! He put them in a bubble mailer and protected and wrapped the chips in additional bubble wrap! U.S.P.S. still managed to break one of the chips not to mention they took over a month to deliver. This chip managed to survive over 80 years but couldnt live through the U.S.P.S.. As ya can see im not a big fan of the mail.
