The refillable MONTANA EMPTY MARKER 20MM T-TIP. Its Tip has the shape of a T and can be replaced. The advantage of this form is that the ductus can be very thin or wide, what makes your drawings and lines dynamic. But as well fill-ins can be done quickly, evenly and precise. You can use water- or alcohol-based 20ml color to refill the MONTANA EMPTY MARKER. Because of its transparent body, the filling level can be realized easily. The tip of the MONTANA EMPTY MARKER 20MM T-TIP can be replaced and the marker is also compatible to MONTANA (BLACK) 15mm and 15mm Shadow replacement tips. Each package consists of 6 markers!
