COMPATIBILITY: The portable case is a travel bag for carrying Pokémon GO Plus. Designed for Pokémon GO Plus controllers to protect your Pok Ball from being dropped, scratched. HARD and SOFT: For the carrying case, the soft inner cushioning on the inside keeps your controller securely in place, so that the thumbstick button on your controller will not be knocked around and damaged during transportation (safer than bundling it loosely in the bag). The splash-proof hard rubbery EVA exterior makes it safer to travel. SOFT and DURABLE: For the inner grip cover, made of soft silicone with good touch feeling, easy to put on and take off, even wash it. CONVENIENT: Portable Case Compatible with Pokémon GO Plus Comes with a carabiner, so you can easily attach it to the belt clip of your jeans, backpack or on your keychain for convenient hands-free travel.
