The two castles arrived very quickly and are really good. The keys fit well into the lock and hook nowhere. Both locks can also be combined with each other, but only "mirror image", the first somewhat confused, because you can combine with each other castles only slightly bent. This is because the part of the castle is the locked, no hole has but a bulge. This can not be used upside down one. But has no effect on the closure. Thus a tab the lock is sliding off the bracket fixed to the bracket. This can include using a small hook. However, this hook is breaking quickly from time. Good, though, is that you can replace it. Annoying it is nevertheless, therefore only 4 stars.
