Rosan series

This reproduces the artisanal technique used at the end of the Edo period to fasten real shark skin with rivets.
With a commitment to authentic cooking utensils and to bringing out the best in delicious food, we have carefully selected and painstakingly crafted these products using the highest quality genuine shark skin.
It can be grated finely, bringing out the aroma and spiciness even more.
Currently, this is an original product exclusive to our company, and we have even obtained a utility model patent.
