This is the "Monster Ball Plus," compatible with Pokémon Let's Go! Pikachu & Eevee, Pokémon Sword & Shield, and Pokémon GO. I used it mainly for Pokémon GO for 2-3 years, but I've recently stopped playing, so I'm putting it up for sale. It's generally dirty, and there are marks from using a strap to tie down the button for automatic catching and spinning PokéStops. It's difficult to see in the photos. The stick is a bit sticky. (I couldn't remove it even after wiping it.) I confirmed that it works with Pokémon Let's Go! Pikachu & Eevee and Pokémon GO. I also confirmed its compatibility with Pokémon Sword & Shield. I'm not sure about the battery life. Mew is not included. I will ship it after initializing it, but if it doesn't work properly, please initialize it again. There are no included accessories.
