These flexible little discs were designed to be the perfect mini marker! They are extra colorful so you can easily track your marker during a runup, they are heavy so they don’t slide around when you are on a hill, and they are flexible so you can fit them anywhere comfortably. Not to mention, they are designed with no sharp edges, so they can double as a soft knee pad :) They fly overstable with very little glide (again, they are heavy) which makes them great point and shoot/point and toss to your friend who always forgets his mini fliers.
