Mine was just Red and Silver not like in the photo
Sorry for the confusion! It can be a bit difficult to show metal color in photos, but the Heart Machine lapel pin uses silver metal as you've noted.
This pin has become part of my pin collection now, and I couldn't be happier.
I have gotten away with wearing this elegant pin to work and I think it's because the heart is such a universal symbol that no one suspects it's from a game...which is perfect for places with strict dress codes! Plenty of curious folks who ask me what it is, though. Once I point out the aorta on it they are satisfied with the answer. Very pleased with the design. Waiting on "The Core" pin to restock so I can complete the Hyper Light Drifter set!
