The technical marker is an ideal tool for marking or taking technical notes during construction or finishing works. Its small tip diameter ensures precise writing. The ink used in the technical marker is German-made, permanent, and free of xylene and toluene. With the use of the DEDRA M89Z06 construction marker, markings and notes are protected from smudging caused by touch or water. This technical marker allows writing on various surfaces, including oily, damp, dusty surfaces, foil, and CDs/DVDs.
