OTR.007 Steelball empty marker

The OTR .007 Steel Ball Marker is similar to the Soultip .007, but features a 5mm steel ball tip instead of a traditional nib. 

These compact markers are perfect for writing on surfaces that would typically damage a regular nib. They work well on hard, textured materials like glass, wood, metal, plastic, and concrete, as well as on rusty, dirty, or even some wet surfaces. Each OTR .007 Steel Ball Marker comes empty, holds 10ml of paint, and is easy to refill.
