No, it usually doesn’t appeal to me. The 2D men are attractive, but to me the 3D figures are not nearly as charming. I also tend to have aggressively conventional decor tastes and a very specific fashion sense which rules out a lot of things like posters and keychains.
The fastest way to get me is to have some plot-significant, good-looking piece of jewelry. Sell it as merch. I’ll probably buy it. Or selling the outfits the characters wear, if I like it. My fashion is somewhat influenced by what I see on fictional characters and I’ve outright bought clothes because they look like something a well-dressed fictional character wore. Also, for this to be “stealth mode”—it’s not clearly from something. For example, if I were a Zelda fan I wouldn’t really vibe with a T-shirt with Link’s face on it, but I wouldn’t mind wearing a dainty little Triforce necklace.
