This is GodHand's Kami Yasuri (God Sandpaper). There are two types: 600 to 1000 grit and 2000 to 10000 grit. I bought these for plastic model making, but I'm selling them because I haven't used them. They are unopened, but have been stored by a private individual, so please refrain from purchasing if you are concerned about the condition. - Model: Sponge Sandpaper - Size: 5mm - Colors: White, Blue, Green - Made in Japan - Brand: GodHand Thank you for looking.
