Rainbow Liquid Chalk nibs come in three categories:
- 5mm bullet point … ideal for smaller writing for detail on menus and other information on non-porous surfaces
- 5mm calligraphy … also ideal for menus etc and where a finer line is required. This nib can also be turned side on for a larger surface.
- 15mm chisel point … ideal for larger writing – headings, big pricing and information. Side on the nib will give a 7mm surface line.
