YONEX Knit Case for Powder Boards YONEX Sole Guard For powder boards Gentle on the board, reduces edge rust with the new BreathSkin material. BreathSkin: New material with high breathability and high moisture absorption/quick-drying properties, providing a high rust-prevention effect. Recommended by the manufacturer for boards 150-160cm. I purchased it two seasons ago. Used it for about a month on a YONEX powder board. As I sold the board soon after, I stored it in a garment case with a desiccant. I think it's hard to find now. I think it's in good condition, but please understand that it is a used item that has been in someone's hands before purchasing. Shipping will be folded as small as possible.
