Cellphone Sweepstakes

I won a sweepstakes prize that is sponsored by a cellphone company. I accessed through my cellphone site and hit an winning ticket. Then I went to the store named Family Mart and show the digital certification. They gave me this and I tried it at home.
携帯電話会社の懸賞サイトで当たったファミマの賞品。サイトで発行された電子証明を店頭にて提示し商品と交換。自宅にて早速試しました。

Oh, I forgot to take photos before I have it......
あ、出来上がりの写真撮る前に食べちゃった・・・
