Mr. Taniguchi's Brilleau STR from the Sewing Department.
About half of the leather got wet in the rain, and as a measure to reduce water stains, I immediately wiped the whole with a tightly wrung towel and dried it.
As a result, water stains are almost unnoticeable, and depending on how you look at it, it seems that the atmosphere has increased.
Thanks to the oil content that is unique to this leather, and the rough texture of the surface, you can use it without hesitation even in the rain, which is the enemy of leather.
