OTR.007 Steelball Squeeze Empty (10ml)

OTR.007 Steelball Squeeze Empty (10ml)

The OTR.007 Steelball Squeeze Marker is a compact German-made writing tool built around pressure, flow, and control. Designed by On The Run, this pocket-sized marker uses a durable 5mm steel rollerball tip combined with a soft squeeze body, allowing the user to regulate ink flow with precision and intention.

Unlike traditional markers that rely purely on felt or fiber tips, the steelball system creates a smooth mechanical roll across the surface—delivering consistent lines even on rough or textured materials. It is refillable, adaptable, and engineered for long-term use with a wide range of inks and paints.

A small vessel. Controlled pressure. Continuous flow.
