Hand Engraver
The red marker is a diamond-tipped engraver which may be used on glass, metal, plastic, or any hard surface. It is also suitable for marking the registration number or serial number onto the windows of motor vehicles. The kit also contains a blue ceramic marker which may be used to mark china, porcelain, glass, vitreous enamel, or any glazed surface. The markers should not be used on delicate items which could be damaged or defaced by the marker tip.
