V1 is a soft, gummy, malleable plastic that is excellent at grabbing chains.
V2 has all of the great qualities of V1 but is a much stiffer plastic.
Both V1 and V2 plastic will float in water!
Alpha is durable, smooth, and tough.
Bravo shares the same qualities as Alpha but is more flexible.
Glow has a similar feel to Bravo but it shines brightly when charged using a UV Blacklight.
Bravo and Glow are slightly more torque resistant, Alpha is true to flight numbers.
X-Outs are those who depart from our usual or accepted standards.
These discs will have slight stamp dropout, no stamp at all, or other deformities in the plastic that will not affect flight.
