Thank you for viewing. Magatama Shihou (Magatama Four Directions) Thickness: Approximately 3mm Diagonal Length: Approximately 110mm "Magatama Shihou," with the three sacred treasures scattered in four directions. The beauty of the design, passed down from ancient times, is outstanding. About 10 years ago, I wanted a real shuriken and purchased it through mail order. I was satisfied with the purchase and kept it stored without opening it. Although unopened, upon inspection for listing, the warning paper and storage paper had discolored. There was no rust on the shuriken itself. Please enjoy it as a work of art and for display purposes only. I have a cat and a snapping turtle as pets. Please be aware if you have any concerns or allergies. Shipping will be via Sagawa Express's Hikyaku Takkyubin. Also, since shipping is done on weekdays, it may take some time before or after holidays.
