I own two belts by K-Boxing. Both are of good quality in terms of leather. The buckles seem durable. My only complaint is that an owner might like to adjust holes. The puncher shipped with the box does not suit the task. So, what I did was I used a cheap metal spoke which I heated and carefully "burned" the required hole in place at a necessary radius. Do that from the inner side not to spoil the surface. One would have to run the spoke several times in order to obtain desired shape. Then, let it cool down for a couple of minutes. Afterwards, carefully remove cinders from the edges and ream the hole with a supplied puncher. The same goes for the case when you need to shorten a belt and provide a hole for a screw in the buckle construction. In this scenario the outcome is immaculate.
