Description

Transform your favorite pins into displayable magnets without damaging them! This adapter snugly slides over the back of a pin, securely holding it in place and allowing it to be displayed on magnetic surfaces. Say goodbye to cutting off pin backs to glue magnets on—this design preserves your pins while adding versatility.

TPU is best for an easy installation and removal!

Features:

  • Non-Destructive Solution: Safely convert pins into magnets without permanent alterations.
  • Secure Fit: Slides onto the back of pins tightly, ensuring a reliable hold. When I say tight, I mean it. It will not go on super easy. This is so that the pin does not just come off unless you take it off. The original version has a 1.21mm diameter opening for the pin. The additional sizes (1.27, 1.33, 1.39, 1.45) may make it easier to put on and take off, and offers variety in pin thicknesses that are supported.
  • Magnet Compatibility: Designed for 5x3mm circular magnets. These are also super tight. They are friction fit and require a bit of force to get in.
  • Two Options Included: Choose between a two-magnet or four-magnet configuration for customizable strength.
  • Versatile Display: Ideal for turning pins into fridge magnets, whiteboard decorations, or magnetic wall art.

This adapter is a perfect solution for collectors and crafters looking to showcase their pins creatively while keeping them intact.
