New item ↓ 59 Pingu Pop-up Greeting Cards - Set of 10 (Envelopes, Letter Sets, Pingu, Pinga, Pingy) Each set includes 1 pop-up message card and 1 envelope. The envelopes are light blue. Envelope size is approximately 11.5 x 16.5 cm. These are originally 350 yen (excluding tax) per set, so 350 x 10 = 3500 yen (excluding tax) worth. The front of the card features a picture of the fish escaping. When you open the card, Robby pops out with a fish in his mouth, as if saying "Here you go!" (lol). It's a card that gives a warm feeling. How about it, Pingu fans? Small children would be thrilled just by these pop-up cards!
