This is a set of 3 pairs of antibacterial and odor-resistant school socks from Tonbo Gakuseifuku. One pair has been tried on and home-laundered. The remaining two pairs are unused. The color is dark navy, and the size is 28-30 cm. Would these be suitable for junior high and high school male students? They will be packaged in a Nekopos size and shipped. Thank you. - Color: Dark Navy - Quantity: Set of 3 pairs - Size: 28-30 cm Color: Navy系 (Navy-based) Stains, tears, odors, etc.: None
