Easy-to-install magnetic safety lock "with Japanese instruction manual." The advantage is that it can be used safely without damaging the appearance of the furniture. I purchased it for 2,300 yen in 2017, but it has been stored at home without being used. ★ When shipping, I would like to use Takkyubin Compact, so please understand that "the plastic parts at the top and bottom of the package will be cut off to fit within 25cm in height." ☆ Immediate purchase without comment is OK. Thank you very much. The product site description is as follows: -------------------------------------------------- [Easy to lock and unlock with magnets] When you bring the magnetic key close to the outside of the drawer or door, the lock part lowers due to the magnetic force, and the lock is released. When you close the door and release the magnetic key, the lock automatically engages. It's easy to open and close because it doesn't require any special skills. *The magnetic key's magnetic force is compatible with doors up to 3cm thick. [Safe design that cannot be opened without a magnetic key] With conventional drawer locks, babies may be able to unlock them quickly by imitating their mothers. With this magnetic lock, it has a structure that cannot be opened without a key, making it safer and more secure! *Please keep the key out of the reach of children. [Cabinet lock that cannot be seen from the outside] The baby guard is installed on the inside, so it does not damage the appearance of the furniture and looks neat. You can rest assured that babies and children will not be able to play with it. It prevents children/pets from mischief and injuries, as well as prevents scattering during earthquakes.
