These are LIGHTLY scented gel pens in beautiful neon pastel shades, perfect for easter cards or drawing on black paper. They quickly dry down to a matte finish and do not smudge. The tip size is about 1.0mm, I'd say. Each pen has 6 shades and the cap color tells you which color it starts off with (you can also just look through the clear barrel to tell which is next). These are comparable to Sakura pens at half the price!
