An Ebony Saya Pin
Total length: 21mm
Head diameter: 7mm
The diameter of the tip of the pin: 3mm
The diameter of the fattest part of the pin: 3.5mm
It is made out of Gabon Ebony with metal lathe, so I make sure to put in the pin to the saya hole whether it fits or not, but the pin of the sizes might have tiny error range.
Please make sure whether it fits for your Saya hole or not before ordering it.
