Mason Pearson combs are manufactured in Switzerland by a contract manufacturing facility that only makes combs. The same, strict quality-control standards followed in our brush making are applied to our combs.Mason Pearson combs are handmade from the finest celluloid material in the world. This is the same material used to make designer costume jewelry, hair ornaments, and eyewear. Look 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 tortoiseshell. The plastic comes to the factory in Switzerland from Italy in a sheet, where it is die-cut into the general shapes of the comb styles. From that point, until the comb is finished, everything is done by hand. 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.
