Thank you for viewing. This is a set of urethane inserts and bottom pads for Tomix plastic cases, capable of storing two diesel cars up to 21M class. One set includes inserts for two cases. - Recommended for storing vehicles up to 20M class. - Cutting the notches at the ends allows for compatibility with diesel cars up to 21M class (for advanced users). - Trains with reduced height can also be stored, but it depends on the actual fit. - Vehicles with roof-mounted equipment cannot be stored. Please refer to the included instruction manual for details. The vehicles in the images are examples of storage and are not included. *High-priced resales are rampant on Amazon.
