Hi there Jo Ann,
Hmmmmmm, OK let me see here.....What are these little pins made of? This is just my interpretation of them, so don't hold me to it 100%!
They are made of a goldtone metal and the backing is a goldtone metal tack kind of back. The colorful front of the pin looks like it is some kind of painted enamel like stuff and then covered in a highly lacquered clear acrylic coating. Or it may just be a very shiny high gloss paint that these metal pins are painted with. Something along those lines anyway!
Anywho, they're cute as anything and really seem to be very nicely made for a nice price! I'm putting one on my jean jacket pocket and one on a hat I wear around to garden.
I speak to Lani frequently and will ask her what they are made of to let ya'll know.
