Ever since ivory was banned John has been looking for a substitute that has all the same characteristics...and is just as beautiful! Man-made plastics may come close but they just weren't close enough. So, he went looking for something that already existed in Nature.. the use of which would not be ecologically damaging. The end result is the John Pearseï¿½ Bone Bridge & End Pin Set! Hand-made from the finest quality camel bone, these beautiful pins are indestinguishable from ivory and will make your guitar both look and sound marvelous! Throughout their lives camels carry such heavy burdens that, as a result, their bones--particularly in their legs-- develop a density that very closely approximates that of elephant ivory. For this reason, camel bone has long been favored by carvers who were delighted by its stability and the ease with which it could be polished. After carefully hand-lathing each pin, our artisans inlay it with a dramatic Parisian Eye in Ebonite and Awabi Pearl and then the set is mounted in a presentation base made from exotic Tegenwood. Each set contains seven bridge pins [in case you lose one!] and a matching end pin.
