I am selling a set of all 5 types of "Pocket Monster Sound Soft Keychains First Edition" (Pikachu, Squirtle, Charmander, Slowbro, and Mewtwo). These items were obtained as prizes at a game center about 20 years ago, so they are not for sale. Touching the switch on the bottom will play a sound, but I cannot guarantee this function due to the age of the items. However, they are about 6cm long and 5cm wide, so they are impressive as figures. I think it's valuable to have the entire series. However, please refrain from purchasing if you are sensitive to the condition of old items. I am also selling the Second Edition, so please take a look.
