This is a set of 8 KATO vehicle case G (for 12 container freight cars) urethane inserts. I was storing KATO's American-style Kokis (double-stack cars) in them, but I recently found the dedicated urethane inserts, so I no longer need these. One insert is in excellent condition, not having been cut. Please ask if you have any questions. I am open to price negotiations. Model train N gauge KATO TOMIX Freight car Koki Vehicle case
