anytime you send anything sharp through the mail- be it pins, scissors, blades-what ever it is VERY IMPORTANT TO put them into a container they CAN NOT POKE THROUGH!!! LIKE A TIN-OR PLASTIC CONTAINER---
IF A MAIL CARRIER GETS HURT (POSSIBLE INFECTION) FROM SOMETHING YOU MAILED YOU COULD BE SUED!!!
FOR EVERYONE'S SAFETY---NEVER EVER SEND SHARPS THROUGH THE MAIL WITHOUT PROPER PACKAGING!!!
