These Glow discs are from the very first production run and do not have the Glow stamp on the bottom side. We have tested these with black light (UV) to evaluate that these are DuraFlex Glow plastic.Some colors glow better than others.

The F Model S has a stable flight and is ready to navigate any fairway with pinpoint accuracy and incredible control. This disc will be perfect for learning how to throw hyzerflip shots that fly straight as an arrow. Thrown hard with a slight hyzer angle, the disc will pop up to flat and ride straight with a mild fade. Players can also get a slight turn by throwing it flat.
