(Material) Punching cow

Punching cow

The punching cow is a leather with a 2mm -diameter ventilation hole in a glossy cowhide of 1.3 to 1.5 mm thick. The interval between holes is 5mm, and these are the best balance derived by our long -standing development and experience.

The larger the ventilation hole, the cooler it will be, but if you fall, you have to think about splitting from the hole. The answer that arrived there was a 2mm diameter hole and a 5mm pitch. These are the numbers required to maintain the strength of leather.

In addition, the surface is embossed. This not only creates facial expressions in leather, but also plays a role in giving leather hardness, and punching cow has the best strength by opening holes in hard leather.
