Kuretake Easy Brush Roll Bokundo Suzuri Wado Suzuri W-50 4.5 Flat 24030 Paperweight Underlay All items were only taken to school once, but I didn't know how to wash the inkstone properly, and it turned slightly white after washing it thoroughly. There is no problem using it. I wrote my name on the box, so I've put white tape over it. Please refrain from purchasing if you are sensitive to used items.
