Jewelry for your guitar A vintage material is reborn Our ivoroid bridge pins, endpins and strap buttons are made of Galalith, a dense and durable casein-based material that polishes beautifully. Popular in the early 20th century, Galalith is found today in collectible vintage jewelry. It cannot be molded; each pin is precisely machined and has none of the unsightly mold lines common to plastic pins. Our ivoroid pins match our endpins and the knobs on Waverly guitar.
