Sakura 3-D Ink Gel Pens
Filled with special 3-D ink, these gel pens make marks that slightly puff up to create color with texture!
For use on hard surfaces such as plastic and glass, as well as on paper- however since the thick ink takes longer to dry, these pens aren't recommended for lengthy writing. Try them for craft projects instead! Glaze pens can make a beautiful stained glass look on decorative objects or jewelry, and Souffle pens leave opaque color even on dark backgrounds.
