High-durability sandpaper set with improved strength and water resistance
This highly durable sandpaper has improved strength and water resistance by soaking the paper in resin. It
is more water resistant than regular waterproof paper, so it is less likely to tear when wet, and the folds are less likely to crack when folded, so it can be used to sand small areas that are difficult to sand with regular sandpaper.
Perfect for the separately sold "FF Board (sanding board)".

Set B contains 4 blades of 1000, 1200, 1500, and 2000 grits, which are convenient for starting sharpening after using Set A. These are easy to transition to the separately sold "Kamiyasu! Polish" series.
The resin is soaked into the paper, giving it some hardness, so it can be scraped off firmly even when using the corners or edges of a file.
It is waterproof so it won't tear even if you use it in water.
Even when folded, the folds on the sand surface are less likely to crack, making it easy to use.
The back side is non-slip, so the sand surface does not get twisted when folded, making it easy to use.
It is highly compatible with FF boards, mini FF boards, etc.
