According to the manufacturer, Sharpie permanent markers are designed to write practically everywhere, however the ink does not tend to stick or last long on non-porous surfaces, like ceramics.
Non-porous surfaces are those which do not allow liquid or air to pass through them. These surfaces also include glass, plastics, metals, and varnished woods.
A "cleanroom" is a controlled environment area (CEA) typically used for manufacturing items that require a low level of environmental pollutants.
Airborne particles are also controlled within a cleanroom!
Sharpie products, such as the Ultra Fine Tip Retractable Permanent Marker, are produced in a cleanroom, making their products cleanroom certified!
A vinyl art eraser is ideal for use with delicate paper projects such as tracing paper and/or drafting film as vinyl is non abrasive material and will minimize damage as well as streak marks.
