we use strong neodymium magnets!
Your copper wearable closes with a waterproof magnetic back and will not damage clothing. Handle gently and it will last for years.
Slide magnets apart; do not let snap together.
Keep magnets away from children and pets, and anyone with a pacemaker.
Keep away from magnetic media (credit cards), smart phones, and GPS devices.
Be aware of how you wear: seatbelt straps, backpack straps and purses can slide your button from its’ magnetic closure.
giving you a sense of scale…
from the top: a 1-1/2” enameled pin, a 1-1/4” pin back with steel closure; a 1/2” waterproof magnet, a back view of a pin with magnet in place; a 1-1/4” copper blank, a 1-1/2” copper blank, and a 15/16” US quarter dollar in the middle for scale.
what is 86/47?
86 is a quotation from the restaurant industry, indicating the kitchen can leave off an offensive ingredient. For example, “86 the mayo!”
I leave to your imagination and intellect the reference for the number 47.
