This is a set of three sound trains. All have been tested and are in working order, but please note the following points: ◆Overall These have been well-played with by a child, so there are signs of use. ・Hankyu The sound may be slightly muffled. (It's difficult to judge if this is a problem.) ・Komachi Something is inside and rattles when shaken. ・Yamanote Line There are signs of use and some scribbles. Batteries will be included. I plan to pack them with bubble wrap and newspaper.
