I make custom items for vroid studio, mainly eye and hair textures, as that's what I'm best at, I might wind up making more items though.
I will always release a free version of my products, but will also have a package with variants for sale, depending on the item.
I'm in alot of fandoms, so some packages will also have variants inspired by shows or games I like.
The free versions for any textures, will always be a black and white, colorless base, as that's the easiest way to change the colors using the color calibration option, in vroid studio.
