This is a combined listing of the KATO 10-399 E26 Series Cassiopeia Basic Set and the KATO 10-400 E26 Series Cassiopeia Add-on Set, formerly sold by KATO (Sekisui Kinzoku). Condition: There are fine scratches and dirt on the car bodies due to use, yellowing of the instruction manuals, and scratches on the cases. The paper sleeves also have scratches, white spots, and minor dirt, so I've marked them as "slightly scratched and dirty." Please check the images carefully. The intermediate couplers have been replaced from Arnold couplers to KATO Coupler Compact A (gray). The destination indicator stickers have been applied to each car, displaying "Cassiopeia Sapporo." The remaining parts are only those shown in image 10. The accessories in image 11, along with the destination indicator stickers and instruction manuals, are included as extras and were all kept as spare parts. As stated in my profile, I have pets at home. I take care to prevent pet hair from getting mixed in, but please refrain from purchasing if you have allergies. This is a used item, so please refrain from purchasing if you are sensitive to such things. This listing includes only the following: KATO 10-399 Cassiopeia Basic Set (6 cars, 1 case, 1 paper sleeve, 1 instruction manual), KATO 10-400 Cassiopeia Add-on Set (6 cars, 1 case, 1 paper sleeve, 1 instruction manual), and the extras in image 11. Parts and vehicles not shown in the images are not included. Please feel free to ask any questions.
