The secret diary with code and melody Depesche TopModel Leoheart is the perfect companion for girls who want to keep their thoughts and secrets in a safe place. The diary features an electronic lock with a 4-digit code that you can personally set and change at any time. After entering the correct code, the diary opens and the melody from Taylor Swifts song Anti-Hero plays (for about 20 seconds), making every opening special and fun. It contains 80 lined and illustrated pages, providing enough space to write down thoughts, secrets, creative ideas, and daily experiences. The hardcover ensures durability and protection of the pages. The diary operates with 3 pieces of 1.5 V batteries, which are included in the set.
