This is shark skin for Japanese swords. The back of the skin has also been thinned. The standard size is 11 inches. Detailed dimensions are as follows: Length: 64.5cm Width: 29.5cm This is a relatively large piece of shark skin. Unfortunately, the parent grains are slightly discolored, and one side of the "nirami" grains is larger, giving it a slightly unbalanced look. It is recommended for those who don't mind the grain pattern. It will be rolled up like a calendar for shipping. #SharkSkin #RaySkin #SharkSkin #GenuineSharkSkin #WasabiGrater #SobaKnife #AntiSlip #LeatherCraft #Repair #Lacquer #Lacquerware #LacquerArt #FishingRod #CrucianCarp #Archery
