This is a rare Koki Niwa limited edition model, with only 500 produced (instead of the usual 1200 for the wood version). It features an inner layer of aramid carbon and an outer layer of fleece carbon. I've only used it for a test drive once or twice, as I was hesitant to use it more. The grip has been slightly modified to prevent discomfort. If you don't mind the modification, please consider purchasing. The original box is not included. If you need the original box, please add 500 yen and comment. - Model Name: Koki Niwa - Brand: Victas - Special Edition: 90th Anniversary Model - Limited Production: 500 units Thank you for looking.
