This is a Wonderswan console. It's a rare color that was sold as a set with a Digimon game. It works without any problems, but the polarizing plate has deteriorated. Therefore, the screen is not visible without the polarizing plate, and you will need to prepare one. You can search for polarizing plates online, or if you ask in the comments, I can answer your questions. I will sell it as a set with the Digimon Adventure 02 Tag Tamers game and a communication adapter that can be linked with the Digimon Pendulum, etc. I can replace the polarizing plate for an additional 600 yen.
