Clothes looking a mite tired after too many hours in the saddle? Shirts showing a bit of age - not to mention blood, sweat and engine grease? Why not use a fetching pin like this one here to draw the eye away from some of the more telling stains in your ensemble?
Yes sir, this pin will impart a certain touch of class to its wearer that's sure to be noticed and regarded favorably by everyone from colonists to city dandies. May even get you an invite to the big shindig, though course we can't say for sure.
1.5" buttons are the perfect size to be able to fit anywhere but still be noticed.
