Pokemon Center 2015 Poncho Pikachu Campaign #1 Mega Slowbro Mini Hand Towel. It was only sold at the Japan Pokemon Centers in December, 2015, for a very limited time and in very limited quantity. It is meant to be a hand towel, but it can be used as a face towel or a handkerchief too. 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.
