ONE TIME OFFER: Grab one of my horse training flags for just $14.99 (normally $19.99) as a special offer on this page only. These 20" x 20" flags are made from ripstop nylon and come with a lifetime guarantee. These flags have mass and also make some noise so the horse can more easily see and hear the flag's position allowing him to better understand which direction you're asking him to move. It also allows you to move your horse's feet with indirect pressure without using physical contact. The end result is a horse that responds accurately to your body language which develops a stronger comprehension of what you're asking him to do.
