This item was stored at home. It is a paperweight made to commemorate the abolition of the Toei Ginza Line. It is made of 61KG grooved rail. (Photos ①③) It seems to be a commemorative item received during a stamp rally event on the Toden Arakawa Line in 1984. (Photos ②④➄) I believe this is a rare item that is no longer available, so I would like to offer it to those who are interested or collecting such items.
