These Bic Velleda 1701 Drywipe Markers provide premium writing and sketching performance with your whiteboard. The alcohol-based ink glides on smoothly and erases just as easily, and is low odour. The markers feature a strong acrylic tip that won't bend or retract into the barrel, even with heavy use. The bullet tip delivers a 1.5mm line width. This bulk pack contains 48 markers with black ink.
