4mm Steel Ball Replacement Tip

These 4mm Steel Ball Replacement Tips come in handy when your old steel tip clogs, breaks, or you just want a fresh new steel tip to get busy with.

These fit our Colorz Premium Steel Tip Markers, the Grog Driller 04 RSP, the Grog Buckshot 60 RSP Refill bottles, and the Grog Driller 04 EPT empty as well as any older Grog Metal Heads you might have.

The 4mm steel ball lays down a heavy, solid line on hard surface including metal, glass, wood, plastic, and concrete.

They also write on rusty, greasy, textured, and wet or dry surfaces and screw right on to the Grog Buckshot 60 RSP 60ml Refills.

They’re made of industrial grade steel and solvent resistant plastic and they last for a pretty long time. These are just like a new nib for your mop, only it’s a steel ball that you can use on any surface.
