Introducing Stabilo Markdry marker pencil for use on whiteboards, chalkboards, show me boards, glass and flipcharts, lasting up to five times longer than a liquid whiteboard marker. With constant bright colour output until the last stroke, Markdry easily erases with a damp or dry cloth on non-porous surfaces and washes off hands and clothes. There is no cap to lose, it will not dry out like a standard liquid marker and there is no bleed-through on flip chart paper. Keep it sharp with the two sharpeners included in this pack. Ideal for school, office and home use. Pack contains 30 Black Pencils.
