Here's a prototype of the Retired rescue Swimmer lapel pin, I haven't ordered them yet, but may do so soon.
It will be 1.75 inches wide, about an inch tall. Sliver plated, almost 2 MM thick, with two pins on the back.
So far it's getting good feedback, if I sent you the link to this, let me know what you think. If I order them I'll seel them through this website. Price is YTBD. Stay tuned.
