Game Boy Advance Top Shell - Wave

Hey, I've hand drawn the wave on these GameBoy Advance top shell. There was supposed to be a bottom one coming with it but I messed it up, so I'm selling this top shell on its own for very cheap. This listing is for the shells only, the system is not included. The shells aren't official, but as you can see in the pictures, the system fits inside.

The shell have a 2K matte clear coat on them. The background is painted using Createx water based paints. The wave was drawn using an isograph pen.
