I purchased two sets, and kept one set for storage. I am selling the unused portion that was kept for storage. Of course, the neck warmer is also unopened. Product Description: This is a limited edition set that combines a commemorative book that looks back on the history of the fierce battles of the two universities, who have both led the Japanese rugby world in name and reality, with a reversible neck warmer that incorporates the colors and emblems of the rugby clubs of both schools, imagining the spirit of no-side, for the 100th tournament. The regular price is 4000 yen.
