Keep your electronics from going barefoot, give them little rubber feet! These small sticky bumpers are Adafruit's favorite accessory for any electronic kit or device. They are sticky, but not impossible to remove. They're small enough to fit onto any board, and have just enough height to give clearance to thru-hole soldered components. Adafruit love them so much they include them free with every Arduino they sell, but they've also had requests to carry them seperately. Comes in a pack of 4 pieces.
Bumpers may vary in style depending on Adafruit's supplier but all are approx 8mm diameter and 4mm tall.
Made of Polyurethane.
