These replacement buttons are perfect for anyone looking to restore or customize their Nintendo Game Boy Advance SP. Whether you want to give new life to an old console or add a personal touch, these buttons are the way to go. They come with all the necessary buttons for a complete upgrade. The buttons are easy to install, but you'll need a tri wing screwdriver (not included) to open the console. The L R shoulder trigger buttons are made of nylon for durability, and the rest are ABS plastic. Just be careful when replacing the triggers to avoid losing the tiny springs. The buttons are compatible with original or third-party housings, but note that the volume slider is only for AGS-101 models of GBA SP.
