It’s a custom RGB mouse bad with my business logo on it. I order it on Amazon Amazon RGB mouse pad
Amazon has them. Here's mine I had done. https://i.imgur.com/6DEgYdC.jpeg As to an even glow there isn't any that I know of that will do that perfectly. None of them have LED that actually go around it. They have LED only in the control box that shoots the light around similar to how an uncovered fiber optic cable would work. So it's going to be the brightest next to the control box.
Worse comes to worse and you don't like it, Amazon has the most painless returns of any E retailer. Just have to ask for a return and then drop it off at a UPS or Kohl's store and show them the QR code Amazon gives you. You don't even have to repack it in a box. I like how mine turned out anyways. https://i.imgur.com/55KG7Oo.jpg?1
