Souffle White 3D Opaque puffy Ink pen by Sakura. Works on light and dark surfaces, with writing you can feel. 0.7mm bold tip. Write slowly for best effect and allow to dry completely. Dries to a delicate fluffy matte effect. Replace cap when not in use. (Tip - I have used may Sakura pens and find when they arrive the have a little bobble of coating on the tip. I carefully remove this and set aside, replacing after each use and this helps to stop tip drying out).
