These are parts needed for horizontal expansion. They are used to replace the original panels. I tried using them once, but it turned out to be inconvenient because it allowed the cats to move between the cages, so I stopped using them and they ended up never being used. Instructions are included. Both the connecting panels and the left/right connecting parts are available in sets of two. There is no original box, so they will be packed using appropriate materials. Direct pickup is also welcome. (→ Price reduced to 2,000 yen.) I can deliver to the Nakai PA on the Tomei Expressway. Please feel free to consult about other meeting locations. The 3-tier combination circle that I was selling at the same time has sold out, but I plan to list the same item again in the future.
