This nifty little item combined with a smooth surface becomes a fully-functional Reflex Punching Bag. The bag it self is built like a speed bag but its jacket is heavy duty PVC to allow for hard impact. It is connected by a spring stem which allows the bag to bop back at you & also provides resistance as opposed to a speed bag which bounces free. The bag comes with a suction base but with a little rigging it can easily be attatched to your speed bag holder or any thing else that can recieve or have a bolt attatched to it. While this item was desinged for playful recreational punching it may also serve as an econmical way for the home trainer to add a Reflex Bag to his/her training regimen. This item would be great for recreational Martial Artists who want an inexpensive home training device that builds hand speed, coordination & accuracy. It is equally great for those with an office who want to blow off some stress with fun punching, keeping the kids busy or teaching juniors how to throw a punch. The buyer will pay shipping & handling of $9.00 which will include Guaranteed Delivery. K05
