Does anyone know the specifications of the Ketsui bosses?

[Nose Laughin]

Might be a bit of an odd question, but does anyone have a photo or else of the Ketsui bosses with their lengths and widths and weight readable? They were sold as stationary at the 2018 Matsuri, and there also appears to have been a screensaver with them in the same year, though I can't find either. So far I've only got the Stage 1 and Stage 4 bosses (Bullfrog and Cinderella Amber); I'd really appreciate it if someone were able to help me out here with a picture of the stationary or otherwise.
