Use only once a day (1 time). I purchased this new for 18,000 yen here. Since the men's 27.0 cm (I am a women's 26.0 cm) is quite large, I will sell it at a low price. *Used once. Please note that it is not new. The following is a copy of the previous seller's introduction: Commonly known as TRIPLE BLACK Popular all-black The model number is different from the regular product. This is the real triple black model. The side construction, specifications, and materials are different from the regular product, giving it a more luxurious feel, blackness, and gloss, making it a rare model. This model is not currently available on the market. Because it is a new, unused item & golden size, it is traded at high prices in some shops. - Brand: Nike - Color: Black - Model: Triple Black - Model Number: 537384 090 Main color...
