I have two Mook Jongs for sale which I constructed before many PVC Mooks where even available.

They are both different as the shorter one is great for wrist traps and side knee kicks. The larger Mook is a traditional form but each of the three arms can be pushed back in different configurations for individual training or for two seperate students (front & back) training.
They take a licking and keep on ticking. Price is firm for the pair. Text me at show contact info
