The TOPModel diary only opens when the correct four-digit code (personalisable and changeable) is entered. Then a top hit plays (approx. 20 seconds). The outside of the diary has a great double model motif and a print with lots of colourful stickers/batches. Inside, 80 finely lined and colourfully illustrated pages are waiting to be written on. The journal is secured by an individual number code, which can be entered on the keyboard on the cover. If the entered code is correct and the journal is unlocked, sounds for approx. 20 seconds. Dimensions: approx. 20.5 x 15.5 x 3.5 cm.
