KAZUYUKI KUMAGAI ATTACHMENT (Kazuyuki Kumagai Attachment) GUIDI NOVA PEL Oil Horse Butt Side Zip Boots. These boots use Italian leather made by NOVA PEL, a former horse leather specialist tanner of GUIDI. Compared to cowhide, horsehide has a smoother grain. "Horse butt" refers to the part of the hide that includes the cordovan layer, which is the rear portion of the horse. Its fibers have a "vertical, densely packed, and extremely fine fiber structure," making it very durable and giving it a unique atmosphere. There are wrinkles and minor scratches typical of natural leather due to several wears. I believe this item is in good condition with no significant damage, but please understand that it is a used item before purchasing. Size: 41
