Power check completed, but slight choppiness and flickering are not considered. This is a customized model based on the 98997 set, modified with a PS23 pantograph for low-clearance tunnel measures when transferred to Matsumoto Depot after cold-region modification. This is considered junk, so please understand before purchasing. No case included, and there are no accessories other than those attached to the vehicle. Shipping will be via Nekopos with cushioning material.
