Pokemon Center 2018 Saiko Soda Campaign Pikachu & Eevee mini hand towel. "Saiko" means "best" or "awesome" in Japanese. This towel was only available at the Japan Pokemon Centers in May, 2018, for a very limited time and in very limited quantity, during the Saiko Soda campaign. It can be used as a face towel, hand towel, or even a handkerchief. Made of 100% cotton. NOTE: To keep the colors from bleeding, dont leave the towel wet for long periods of time. If you wash it, wash separately, as colors may fade or bleed the first time you wash it.
