First of all, I wasn't sure what they meant by the tri-colored pencils and then when I got them, I saw that the pencils are triangular in style. They are very interesting and super easy to hold. These are just what I was looking for and work well with the Faber metallic pencils I just purchased.  The lead (or whatever it is) is soft yet doesn't break easily. The colors are vibrant and I can't get some beautiful sparkly accents with using these and the Faber metallic colored pencils and I don't need  to use a metallic gel pen. Each of the pencils offers a rich, intense color and when I use them with their matching metallic colored pencils I get a beautiful combination. I am hoping that these colors will give me more inspiration to work in my adult coloring books. Very excited to continue using these!
