God002 Miyuu U15 22 New Now

I need to gather information on its design, materials, ink capacity, nib options, and user experience. Since I don't have personal experience with this model, I should mention that and focus on general information about fountain pens, possibly linking it to similar models. I should also highlight features like materials (plastic vs. metal), nib material (stainless steel, gold), ink type (converter vs. cartridge), and price range.
