Mason Pearson combs are hand made from the finest celluloid material in the world. This is the same material used to make designer costume jewelry, hair ornaments, and eyewear. Looking carefully at the "tortoise" pattern of our combs, you will notice the 3D effect of the "shell" pattern. This is the result of an internationally patented process that replicates natural tortoise shell. Each tooth is cut, one at a time, on a special saw. The comb is then tumbled in a polishing drum to smooth the surface. The next step is hand polishing to remove all burrs, sharp edges, and surface imperfections. Finally, it is buffed to create the high gloss finish. Made in Switzerland.
