I walked to the nearest post office to purchase stamps for my letter the other day. Now the postage for a sealed letter is Yen84, so I asked the office staff to get me ten pieces of ordinary ones in total, considering their future use. Then, she said, "How about the sticky type of stamps available now?" and showed me a colorful, cute design sheet of stamps. It's a Pokémon stamp sheet! Each one of them has unique, lovely Pokémon designs that I hesitate to consume! But, I will have lots of fun sending letters to my friends with these kawaii stamps this summer.
