I really love these pens! They are highly dependable for quick colors on my
notes and projects at school. They are also great doodling pens. I've posted
sample drawings on my instagram: alohadoodle. I like using them on thicker
papers because they will bleed through on very thin note papers. The the pens
are skinny and short so they fit rather well in my pencil case. I recommend all
18 colors. Just wish they had a yellow.
