Review: Très pratique et bien pensé pour bien conserver la clé dans la boite à clés! - Pour tous ceux qui ont des enfants étourdis, ou pas mal de personnes qui doivent passer en votre absence : si vous ne voulez pas que quelqu'un oublie de remettre la clé et que le suivant se retrouve devant une boite vide! La longueur est suffisante meme pour une boite installée du côté opposé à la serrure (besoin de discrétion). Super trouvaille!
