Listing is for a tomtoc sling bag for the Nintendo Switch / OLED Switch. It can fit your Switch, the dock, joycons, a pro controller, power bank, cables, 20 game cards, and other accessories inside. You may be able to fit other handhelds inside as well if they're around the same size as the Switch. It was used to hold my handheld for around a month until I got a different case but I never took it out the house so it's like new.
