These are VENUM shin guards. I bought them new for 16,000 yen and used them only once on a heavy bag at a kickboxing gym, so they are practically new. The following is from the manufacturer: Made with high-quality Skintex leather. Additional padding with high-density foam (shin and instep) to absorb impact. Lightweight design does not restrict movement or speed. Equipped with large hook-and-loop straps for a non-slip fit. Made in Thailand, handmade. I am selling these because I have become too busy with work to go to the gym. If you are looking for high-quality shin guards, how about these? They are almost new, but they are still used items. Please purchase only if you understand this.
