This is the last of the 3 discs (TeenPro, FiveStar) from Yikun sports that I own. It’s a special winter edition – that means the plastic material is more durable and soft. Best for playing at -20°C – +5°C. Normal sport discs get stiff and brittle and break in cold temperature. I saw an ultrastar disc same years ago break into more than two dozen parts when we played in Norway. Other companies also produce special winterdiscs (for example Daredevil).
You can find more about that disc at the company page.
