My child loved wearing these, so they're somewhat dirty and have some pilling, but you can never have too many spare socks when they're little, right? They're still wearable, so please use them. The Tokaido Line ones are the cleanest – the Keihin-Tohoku Line ones show quite a bit of wear. Baby socks with train designs, set of 4 pairs, comfortable cotton blend. - Design: Illustrated with trains - Size: Approximately 12cm - Colors: Blue and beige - Design: Set of different train designs - Material: Cotton blend
