This is a Dr. Yellow and Tsubasa Shinkansen bento box. It's from a bento box purchased at the Railway Museum, Tokyo Station, etc. It has been brought home, washed, and stored carefully. ⚠️ The Kamome bento box is sold out, so this is now a 2-piece set. I am also selling other ekiben (train station bento) containers, so you can mix and match!
