All patches have velcro back, if you get 10 or more there only $3 each. Check other listings for more patches! I can fit a ton into a padded flat rate envelope for $8 shipping. If you just want 1 patch mailed with 2 stamps shipping will be $1.25 but won't have tracking or insurance. I do not recommend using this method as I cant guarantee it will get there at all. The post office frequently loses these.
