You're right, sometimes those boxes aren't the best choice, the PO also has other various size FREE Priority boxes that are for weight based mailing. I keep on hand some of all size boxes ordered online shipped to me free from post office. Plus if someone were shipping just 1 to 2 thousand tokens or balls those could be sent in a Flat Rate envelope. For extra protection you can get a SMALL Video Priority box free and package tokens/balls inside and then put it in the flat rate envelope - ship for only $3.85 anywhere in USA.
