Most floor hockey sets are made for use indoors and quickly wear out when used on the hard playground. These sets feature extra thick outdoor plastic blades that will last for years. Each set includes 12 sticks - (6 White blades/6 Black blades), 2 speed control balls and 1 instruction booklet. Blades are not to be used on gymnasium floors.
