The Reko putt and approach disc by Kastaplast is neutral in flight, great for many arm speeds and styles of play!

K1 Soft plastic (previously known as K2) is super grippy and flexible, but also very durable! This plastic also tends to have slightly less stability than regular K1.

NOTE: The Do It Yourself line from Kastaplast is a series of blank top with bottom stamp discs intending to be used as a blank canvas for all the disc artists out there!
