1. Paper quality has an impact on how smooth different coloring utensils work.
For example, I tried to use Sharpies in a coloring book without much success.
Therefore, I felt that these pens were inferior to color with.
When I tried them in a book with quality paper such as ColorIt brand,
the color lay down was much smoother.
The ultra fine point pens work great in small areas.
These pens are a great inexpensive way to add to your color collection.
2. Some pictures to color can be a bit confusing.
It often helps to turn the picture upside down to figure out what a shape is.
This also works on puzzle books such as find the object and find the differences.
