A "number matching lock" is a lock that can be unlocked by entering a combination of multiple numbers. It is common to enter a preset PIN such as "21-42-7" by turning the dial.
But there must be a right-brained person in the world who says, "I hate numbers!" It would be unfair in the world if there were not only "number matching locks" for left-brain type people, but also "picture matching locks" for right-brain type people to combine and unlock pictures.
"IMAGE LOCK" is a lock for such a right-brained person. It can be unlocked by entering a combination of pictures such as "cat-heart-umbrella" instead of numbers.
Since the author is a typical left-brain type, I can't remember the combination of pictures. However, the seller of "IMAGE LOCK" explains that if you make a little story with this mark, you will not forget it. For example, in the case of the above "cat-heart-umbrella", "Cat loves being out in the rain".
The developers of "IMAGE LOCK" claim that picture combinations are much easier to remember than number combinations and can provide the same level of security as number matching.
I don't know if this claim is correct, but somehow I feel that this lock is hard to break. Even if there are still people who are called lock breakers, wouldn't they be motivated if they were in front of a lock with "monkeys," "butterflies," "pigeons," "stars," etc.? Besides, when I broke this lock, I feel like the treasure isn't sleeping over there.
The price is $ 3.99. It delivers to 35 countries around the world, but for some reason it does not seem to support delivery to Japan.
