Selling because I no longer need it. I purchased this from a weapon shop's online store about 4 years ago. Please check the photos for the condition. There are no major chips or holes in the mats, but please refrain from purchasing if you are overly concerned about minor details. Due to the weight restrictions for shipping, I am selling this in three separate listings. If you wish to purchase all 9 pieces, please purchase listings ① to ③. ① and ② will ship 4 mats each. ③ will ship 1 mat and side pieces. Size: 50cm x 50cm Thickness: 15mm
