Those are fun! They are also super expensive for us to pull off. We have to buy materials(aluminum AND Ti), build, ano, bearing, pad, string, create artwork, and package ALL of them before we sell a single one. It’s a huge investment and risk for us. With a typical run you can release 200 hundred yoyos and see what people think, maybe then do a 2nd run with some custom colors, etc. if people are really interested. The $ from the first run gets passed forward to make more. We don’t own the idea, we got it from Japanese vinyl toy releases. Any “company” is free to give it a go.
