Heavy Metal Pin These are all we have left from August's Pinscription (our monthly pin subscription box)! So unfortunately they are a limited run and won't be re-stocked. If you'd like to take part in our monthly pin subscription, you can sign up now! You will receive 2 surprise pins every month. Info: As always our Heavy Metal Pin Badge comes with a metal clutch so you have that extra added security. Measuring at approx 30mm, this is this is the perfect size for your lapels! Add our locking pin back for extra security.
