Kato Hapi-Line Fukui Series 521 (Standard Paint + Full Wrapping) 4-Car Set Special Planning Product Product Number: 10-2014 This is an N-gauge model of the Hapi-Line Fukui Series 521. After purchasing new, I only test-ran it and then stored it. I didn't see any noticeable scratches on the vehicles at a glance. Also, there were no particular problems with the running. However, this is a visual inspection by an amateur, so please be aware of that. Thank you very much.
