How do you write letters on glass?

If you want to generate long lasting lettering artworks on glass, choose oil-based markers, such as the ones of Sharpie. The Sakura Pen Touch and the DecoColor paint pens (the latter is produced by Marvy Uchida) are oil-based as well and they are good tools to write on small glass projects.
