Pokemon Center 2018 Saiko Soda Campaign Pikachu & Eevee smart phone cover. "Saiko" means "best" or "awesome" in Japanese. It was only sold at the Pokemon Centers in Japan, for a very limited time and in very limited quantity, in May, 2018, during the Saiko Soda campaign. This is a case that your smart phone can fit inside (NOTE: This is only a case and not the phone). The case has no set size plastic mold for the phone to snap into. Your phone simply sticks on to the backside of the phone case, so you can fit many different types of smart phones inside. This is an "All Smart Phone" case, so it will fit any maker of smart phone, as long as the size fits. Your phone must fit in the size listed below. Please make sure it fits your mobile phone before buying it.
