Model Specifications:
*Note that some products may not be compatible depending on their shape and design.
- The Cat Arms can be connected to models such as Frame Arms Girl and Megami Device using 3mm connection points and ball joints in the shoulders. The arms can also be turned into Cat Paws by swapping out parts.
- The Cat Feet have a 3mm joint in the ankles and a 2.5mm connection point inside the feet, so they are compatible with a variety of items.
- The Cat Arms and Cat Legs of the cat armor can be assembled with or without claws.
- The Cat Tail has four points of articulation, allowing for a wide variety of expressive poses.
- The kit includes Cat Tail connection parts for Frame Arms Girl, Megami Device and Sousai Shojo Teien models. Two types are included for each series: one for regular connection joints and one specifically for the New Flying Base (sold separately).
- Includes two Cat Ear Headbands. The universal type features a band made of synthetic rubber, while the Magatsuki series type is for use with Frame Arms Girl Magatsuki and its other variation kits.
*Compatibility with the Cat Ear Headband (regular) depends on the shape of the model's head. As the headband pinches the head, there is a limit to how firmly it attaches.
