Adafruit Magnetic Pin Back [ADA1170]
These magnetic pin backs have two pieces: a metal bar with adhesive strip and a plastic piece with two strong rare-earth magnets. Affix the metal bar to your FLORA projects-- it's just the right size! Then attach your FLORA project to any garment without poking holes in your clothes. The magnets are strong enough to hold up even a hefty circuit!
We recommend against soldering/brazing/welding to any part of the magnetic pin back, as the galvanized steel plate would release harmful zinc fumes and heat demagnetizes neodymium magnets.
