Plastic holder for marker, to open and close it with one hand.
It is very convenient to use during gemstone faceting, when we need to mark something on the stone. We hold the stone in one hand and with the other we can easily pick it up and then put it back in place so it doesn’t dry out.
The marker is attached by tightening the wing nut and can be changed at any time.
3D-printed in PLA. Marker not included.
