Sorry I didn't get back on here sooner.Is that good.or bad?
I've decided it is good; helps draw your attention to those 5 pencils when you are new to the set. Also, while the other pencils are round, those 5 have 6 sides, another way to identify them.
I know folks told me the Manga pencils refer to the color palette. I have to say, they 'feel' different on the page, and they cover more easily. I don't have to go over and over to get the bold color I want, or to fill in white spaces.
