Extra Broad Chisel Tip 17K Posca Markers
The Posca 17K is the largest and broadest marker in the Posca range, capable of producing bold lines approximately 15mm wide. Featuring a large rectangular felt tip, the marker is activated in the usual Posca way by gently depressing the nib to allow the paint to flow evenly through the tip.
Designed for big, eye-catching work, the 17K is especially popular for street art, window and windscreen displays, signage, and large-scale artworks where strong coverage and vibrant colour are essential.
Like all Posca markers, the paint delivers a rich, flat matte finish that is permanent once dry on most surfaces. When used on glass, Posca paint can be removed by carefully scraping it away with a blade, then cleaning the surface with a quality glass cleaner such as Windex.
