• High strength plastic construction allows the boards to be broken over 1000 times while requiring the same amount of force as on the first break
• Rubber palm-pad provides cushioning for the holder
• The difficulty increases from white belt up to black belt
• Choose from seven different colors and difficulty levels. Each color represents an increasing level of difficulty beginning with white as the easiest and ending with black and the most difficult (following the traditional belt rank system.)

These boards were tested by dropping steel balls of increasing weights on standard breaking boards. The weight required to break a board of the same width varied widely from board to board. An average was taken and the boards were developed to break at that point.

And they do, at the first break and the one thousandth, these boards take the same force to break.

All the boards are stackable for multiple-board breaks. The boards have padding on the back, so that if someone is holiding the board for the break it is more comfortable for them.
