Thank you for viewing! (_ _) Are you having trouble with broken or missing connecting parts? These are 3D-printed replacement connecting parts. Although we haven't lost any, we replaced the ones that easily came off due to being loose! These are exclusively for the E6 Komachi. Please note that they cannot be attached to the E5 Hayabusa. Set Contents: E6 Series Komachi-specific connecting parts x1 E6 Komachi-specific connecting part cover x1 Dedicated couplers x2 (including replacements for when broken) The couplers are basically male type. If you leave a comment, I can show you a picture of the female type couplers as well. Feel free to ask (*_ _) It's also possible to have one male and one female. If you want spares, please comment. You can add them for 30 yen each, regardless of male or female. *The train cars are not included in the set. Please prepare them yourself. The color is a similar red, but slightly different. Please consider it amateur painting. If you do not need the paint, please comment. *Even if the connecting parts are damaged, they can be easily replaced by removing the screws. Please tighten the screws gently. They can strip easily.
