Buttons by H. Mathis
1.5" Black/White, White/Black
Sold as pair
Instructions for use:
"Wear one, and have your outing partner wear the other one to balance out the universe. Never lose sight of the other person for the entire evening. (User may find this difficult on bathroom breaks, if of the opposite sex.) Do your best.
OR
Adorn both of them on one item (shirt, coat, bag, etc). Doing this will cancel out the other one.
DO NOT
Cover your entire body in these pins. People will most definitely think you are crazy."
This button set was intended to be put on a card (as many button sets are). However, H. knew that it would be impossible to place the buttons straight enough, or accurate enough on a card...So he bypassed this option to save everyone (including himself) the anxiety.
