At long last the PERFECT marking pencil!  Will draw on fabric as easily as on paper - there is no dragging, the pencil just glides across the fabric.  The amazing thing is it will erase off like a dream with no sign of any marks. If you don't want to erase the marks away they will wash out with a damp cloth.  Four different coloured refills and a replacement eraser is also available.  Colours are grey, yellow, green or white.
