Grease Pencils (China Markers)
Carmel's Grease Pencils (China Markers) are wax writings tool also called wax pencil, china marker, or pull string pencils. They are best used when trying to mark glossy non-porous surfaces such as porcelain, glass, polished stone, plastic, ceramics and other glazed, lacquered or polished surfaces. Due to the fact that grease pencils rarely scratch surfaces, are non-permanent, and work on wet items, they are also often included in most construction marking sets. However, many artists and laboratory workers also use china markers.
