It comes with 2 joy-con skins, 2 joy-con grips that work great for games such as Super Smash Bros., 2 joy-con wheels to play Mario Kart, a very sturdy carrying case, a nice and durable , Nintendo Switch case that helps a lot with my hand cramps, a 4 joy-con USB charger, carrying case, screen protector... and I think that's all.

Provide bottom protection (except exposed ports) in case the flat surface isn't sanitary, Joy con controllers has to be in case, so have to use external controller like the pro controller
