Suitable for 57mm (approx.) can badges. The sample can badge is not included! The front has a ribbon loop to thread the can badge pin through and a magnet in the center. Includes one ball chain. There is a ribbon hoop on the back to attach hardware, so you can replace it with your favorite safety pin or bag charm hardware, etc. Adhered with sewing double-sided tape, hand-sewing, and a glue gun. Will be wrapped in cushioning material for shipping, but if any parts come off during shipping, please reattach them with your own adhesive. Instant purchase is OK. No price reduction.
