This is a highly valuable, brand new, unopened copy of the original Game Boy version of Pocket Monster Blue (limited edition from CoroCoro Comic). Please refrain from purchasing if you are looking for a truly pristine item, as it has been nearly 30 years since its release. Please confirm the condition in the photos and purchase only if you are satisfied. My product images may be screenshotted and used without permission. I suppose that means it's a good product. Please be careful of suspicious images or screenshot images, as there are many scams involving new and unopened items. This game is the origin of what is now recognized worldwide as a monster-sized hit: Pokémon. Pokémon cards have been traded for exorbitant amounts of money, even hundreds of millions of yen, but it all started here. This is a genuine, completely unopened item. Please check images 3, 4, 5, and 6. If you want to buy an unopened copy, be sure to check these. Initially, it was a limited release through mail order in magazines, with tens of thousands of applications, overwhelming Shogakukan's processing operations and drawing criticism from potential buyers. Nostalgic, isn't it? Due to the value of this item, please refrain from price negotiations. Please confirm the item carefully before purchasing due to its high price. Returns and refunds are not possible to prevent swapping. The item is unused, so I have not confirmed its functionality. Please understand that I cannot guarantee the backup battery. Collectors residing overseas are also welcome. I will carefully wrap it with bubble wrap and ship it via Mercari delivery service. I will ship it with the protective case, which has 97% UV protection, to keep it in beautiful condition. Thank you for considering purchasing! #Game #RPG #GameBoy #Nintendo #GameBoyColor #Retro
