These are very handy! Each marker has the same color but one end is more of a thicker marker but as big as a regular marking pen. The other is a fine tip marker for doing more detailed work. Great for adult coloring books or anywhere you would need a fine point or a marker not as thick as the regular ones.

Ex Output:
positive
