This is a custom pair of official Joy-Cons for the Switch 2, modified using parts from Extremerate. The front shell has been replaced with a black skeleton design, and the ABXY buttons have been swapped for colored ones. The D-pad has been converted. The analog sticks are the original ones, but the tips have been replaced with resin-molded ones. The base of the sticks has been painted and coated with resin. The LR buttons and back panel are original. The Joy-Cons were made using brand new Joy-Cons. Of course, functionality has been confirmed. Because the part that connects to the Switch 2 is not original, there is some looseness. To address this, I've made some adjustments. The carbon fiber pattern cutting sheet visible in the photos has been applied to reduce looseness. Additionally, I've done some resin work to further reduce looseness. While I adjusted them on my own Switch 2, I believe the effect will be the same regardless of which console they are attached to.
