Anti-slip spikes, XL size, Fujiwara Sangyo I purchased these thinking about work in slippery conditions, not just during winter freezing, but the size didn't fit, so I'm selling them. Therefore, I only tried them on once to check the size. The manufacturer's recommended size is XL, 28-30cm. Please refer to the photos for the approximate size. The package is not included; only the main unit will be shipped. Please purchase if you understand that this item has been stored at home.
