Seasoned Pokémon GO players will already be familiar with the Pokémon GO Plus, a Bluetooth-enabled device which allows you to catch monsters and pillage PokéStops without having to remove your phone from your pocket.
The device ships with a bracelet attachment and a clip attachment, but there's a third option coming to Japan tomorrow: an accessory which clips onto the back of the device and allows it to be worn like a ring.
The accessory costs just 400 yen, which is around £3 / $3.50. It also comes with a sheet of stickers that allow you to dress up your GO Plus like a Great Ball, Super Ball, or Master Ball.
There's no word on whether or not we'll see this useful piece of plastic in the west, but in Japan it will be sold exclusively in Pokémon Centres and Stores.
