nothing here...
Ferrees sells concave and convex pearls for saxes. Far as I recall, they are real m-o-p.
I think Ferrees/Allied/Badger sell a pearlescent goo that you can use to form pearl-like fingertouches.
But I'm not much interested in that.
I am having trouble finding pearl rollers and am likewise looking for pearl, amber, bakelite, etc.
I've ordered some stuff from bead catalogs (like for necklaces) but haven't found anything real suitable.
I think Ferees has plastic rollers.
I've had a little success having a local rock shop custom cut stones for saxes. A tiger-eye thumbrest and some decorative lapis lazuli stones to replace missing m-o-p on keyguards.
