Available Saturday we looked around the lock to close the box "castle" but found !! This lock is nevertheless well on the accessories, right ?? And of course impossible to return this game because all the blisters were open when we noticed the lack !! Disappointment for the child, parents and disappointment to disappointment for the sponsor (me) .... I do not know if this error comes from amazon or manufacturer but I am extremely disappointed with my purchase and it is not a good point in favor of amazon !!!
