Wachierudo Diyan Cat Fountain Pen - Diane of the Celestial Sphere IP635366 with Cartridge Converter Ink Color: Blue Black F Shape (Fine Point)

Replying to myself. It's out of stock, but there is a pen with cats and a sort of galactic theme. I got one but haven't tested it yet. I've seen it on eBay as well. https://a.co/d/0ddjlWuD
