Plain Horn Risha/Plectrum/Pick
Nothing beats the nature, and it applies to Oud Plectrums too. The best and most dense material for plectrums are the animal bone or horns as is approved since men has played stringed instruments.
These oud plectrums are made of domesticated African Buffalo horns and not from endangered species!!!
The plain horn plectrums need to be sanded(400grit) at both ends to obtain your desired thickness.
The color is subject of change as it's a natural material and is never the same!
