Thank you for viewing. These are special tabi (split-toe socks) used in power line construction. Size: 25.5cm New and unused, but due to poor storage, the inner fabric has pink discoloration in places. Upon investigation, it was identified as yeast (red mold). It seems possible to remove it with baking soda, lukewarm water, etc. The extent of the pink discoloration may be difficult to see, so please check the images. The pink discoloration is widespread. It's quite severe. Please only purchase if you understand these conditions.
