These minis are made of OG Glo material and 100mm in diameter. They are quite heavy so they won't slide around as a marker, they are flexible, and they even double as a kneepad! The flight plate is thick and the disc is designed with no sharp edges so you can comfortably place your knee in the bottom of the flight plate. 

glO-G Silicone Rubber - Our glO-G material combines all the great things you love about OG with the ability to GLOW, super well we might add :) glO-G is as good as it gets for stopping ground-play and roll-aways. Being one of our floppiest materials it excels at absorbing impact and extremely vibrant colors help your disc stand out on the course and give each disc a unique look, day or night. They are awesome for normal rounds, glow rounds, or even playing catch at night due to it's flexibility!
