Stabilo Pencil Black
Stabilo Pencils are valued for their writing ability on porcelain – smooth and with a fine line, as the Stabilo Pencils can be sharpened with any pencil sharpener to the size of point that you need. No crumbling – they make a nice, smooth line which will fire off in the kiln and leave no mark on the porcelain / ceramic.
Also writes well on glass, plastic and metal, lead with high-quality pigments. Tip width: 3.3 mm.
