サニー・ザ・メールスネイルからのぬいぐるみとカタツムリ郵便の週刊レター（対象年齢3〜8歳）

My daughter counts down the days until Sunny’s letter arrives—she’s only four, but she already recognizes her own name on the envelope and carries it around all afternoon. The weekly routine has genuinely turned into the highlight of her week.

The envelope art is so cute that my son insisted on displaying it on his nightstand all week. It’s genuinely helped him practice patience too—waiting for Saturday’s letter is a big deal now.

My 5-year-old lights up every time she sees Sunny’s envelope in the mailbox—it’s like getting a surprise from a real friend. The weekly letters keep her engaged with the animal facts and travel stories, and she even tries to write back to Sunny.
