Baby socks with the design of the Shinkansen N700 series. Size: 9-15cm, with non-slip grips. Short socks. - Model Name: N700 ADVANCED - Size: 9-15cm - Design: Shinkansen design - Non-slip: Yes Thank you for viewing. How about these for children who love trains and Shinkansen? My older child loves trains, and these were given to us, but they were already too small, so they are unused. They are short socks, so they are also good for practicing putting on socks by themselves from the time they start walking! ✨
