Czech Glass or Bohemian glass spike beads are 12mm at the base and 18mm long, with a smaller size ( 7x17mm) and an even smaller size (5x8mm) now in production. We are told that these can be considered handmade. They are not pressed like round beads in an automated fashion, rather they are hand pressed, and the base bead shape has to be extracted manually from the mold.
Very beautiful and fun to work with. What can you do with them? We would love to see!
