We have a range of retro-fit strap buttons. These are all hand-turned in the US. We have a range of attractive materials to match or complement your guitar. The ivoroid pins are made from Galalith, a hard plastic which was widely used in the 1930s. It turns well and takes a high gloss when polished. Tools to help with the fitting of strap buttons are also listed.
We also have Larrivee vintage-style metal strap buttons.
