This is a Flowin training mat set, also known to be used by professional soccer player Yuto Nagatomo. It's not the large black version, but this one is sufficient for training. I haven't used it very often, but I bought it three years ago, so there are some scratches and dents. However, as it's training equipment, I think it's perfectly acceptable for sports enthusiasts and athletes who use it frequently. Therefore, please consider this only if you understand the condition.
