Empty 6.5mm Valve Marker
The Empty 6.5mm Valve Marker is available in both a chisel tip nib and a bullet nib and works well with both ink and paint.
These markers are easily refilled by unscrewing the cap on the bottom, just like the OTR .4468 Superflow and OTR .4201 Soultip Painter markers. No need to unscrew the head & pull the valve out, just twist the bottom cap, fill and screw the cap back on.
These have the old school yellow fiber nibs so they stay nice & juicy so your lines won’t streak, and they mark just about any hard surface including metal, glass, wood, rubber, PVC, plastic, etc.
The body is made of hard plastic and holds about 20ml-30ml of ink or paint.
