sakuraa PENTOUCH Paint Marker 2.0mm Medium Mark On Any Thing Glass/Cloth/Metal  (Set of 1, Black)

Sakura Pen-Touch paint markers feature bold, opaque ink that writes well on a variety of surfaces including light and dark papers, cardstock, plastic, wood, glass, porcelain, and metal. Use them to decorate anything from letters and scrapbooks to glassware and home decor. This pen can be used with both matte and glossy paper, but the ink shows up best on non-absorbent surfaces. It is permanent on most surfaces but not on glass or ceramic. We recommend testing it first to make sure that it works well for your purposes.
