Review: Une poupée avec deux looks différents - Ce qu'il y a de mieux dans cet ensemble c'est que la poupée peut avoir deux looks différents : un look sport et un look habillé. Les enfants aimeront également les accessoires qui sont personnalisés pour chaque personnage Monster High. Le coffret avec son jeu de clés est vraiment très amusant . C'est une bonne idée car cela diminue les emballages et permet de garder la poupée et ses accessoires à l'abri de la lumière et de la poussière.

The designers really took their time and went out of their comfort zone with these dolls and it paid off! You get a really cute coffin shaped locker that you can display on your wall if you want. There’s a set of keys that you dip in water that change color to match the doors on the locker to open and inside you’ll find all kinds of really cool accessories.! And you do get a Lagoona doll with it! And this Lagoona doll is breathtaking! Her hair is really long and soft! All the accessories just add to this and have endless mix and match possibilities! Great item for a collector or a little one who is discovering their love for Monster High! Plus the price, $30, for everything is an amazing deal!!

### ⭐⭐⭐⭐⭐ Excelente compra
*by A***N on 2 September 2023*

La verdad es que me animé a comprarla por el hecho de que tenía 43% de descuento, sin embargo es una muñeca que vale totalmente la pena. Es súper linda, el cambio de ropa es muy bello y el cabello tiene una calidad excelente.Incluso me atrevo a decir que es mucho más bonita que su edición core. Ahora quiero completar toda la primera línea de Skulltimate secrets 🥺❤️
