Can the edding 4200 porcelain brush pencil be used on glasses, cups or mugs for drinking without hesitation in the drinking area?
No, that should be avoided. If the glass, mug or cup is to be used in daily use, we do not recommend it under any circumstances. Colour particles that might come off during the use and cleaning process can get into the organism, but the porcelain brushes are suitable for the decorative design of glasses, cups and mugs.
