White plastic, beautifully molded plastic classic lady heads are the type you can put on buff top cabs to make them into cameos.....they put them on plastic flat top stones back in the day! I was so thrilled to find these on my last buying trip because you can use them in collage, mixed media design, on paper arts, and also in jewelry making! FLATBACK....easy to work with. Glue to the top of blank you've textured and colorized, or embossed. Hey! I wanna go try that myself! TWELVE in the package. 18x19mm. Grab them while we have them....once sold out, they will be gone for good!
