We're all in support of forging your own path and making your own career in YouTube, Twitch, cosplay, or anything else, but cosplayer Belle Delphine must be in a very niche market with her fans because she's selling her own bathwater for $30 a jar!!
The product name is "GamerGirl Bath Water" and for all we know it could just be normal tap water that she is selling to her fans by advertising that she took a bath in the water.
Most people sell a t-shirt or socks, but Belle Delphine sort of caters to an adult market so just beware if you try to look her up by the images that pop up because they are definitely not safe for work (NSFW)!!
