Arcos par Puca are crescents with three holes drilled through the flat side of a bead. Minos par Puca are barrel-shaped beads with one hole through the middle. Arcos and Minos work perfectly together. Kheops par Puca are triangular in shape with two parallel holes. All three shapes were designed by a French beader Puca and are a great addition to the one-hole and the multiple-hole Czech glass beads.
