Established in 1949 in the USA, Chartpak Inc. began life making and supplying graphic design products. They may be not as well known in the UK as some other manufacturers, but the Chartpak Ad Marker with its Tri Nib that produces three different line widths is an excellent artist’s marker that is extremely popular with artists in the USA and Europe. The Chartpak Blender Pen was originally designed for blending different Chartpak marker colours, but it is now renowned for its ability to transfer images onto different surfaces. There are lots of tutorials on the web on how to transfer photos using a blender pen. Check out our full range of Chartpak pens below.
