Here is the description from JetPens:
In this winning combination, Pilot has combined two of Japan's most popular items, Hello Kitty and the Hi-Tec-C. A collection of nine adorable figurines adorn this limited-edition collection. The figurines include images of the standard Hello Kitty, Charmmy Kitty, as well as her charming mouse friend. Each set includes a RANDOM set of figurines, so what you receive will not necessarily match the picture displayed. The figurines on the caps can also be removed, so when you are done with this Hi-Tec-C you can always transfer Hello Kitty to your new Hi-Tec-C for another round of joyful writing.
