These super popular discs are Star plastic and have a halo effect on the outside of the disc using multiple colors. Overall I have heard most people claim they are more overstable and glidier than the normal runs of star plastic in that mold. I cannot confirm nor deny that claim just passing along what I have heard.
We do our best to accurately describe each disc. Be aware there may be minor storage wear on any disc I list but anything significant will be mentioned in the items description. All of my discs are new/unthrown unless mentioned as USED in the title or description.
