Child Safety Magnet Lock

My apartment's kitchen and bathroom cabinets have been repainted white so many times that the majority of them cannot close. Instead, they hang open anywhere from a few centimeters to four inches.

Since the property manager will not permit me to make any permanent changes, I need suggestions for some type of latches that I can easily remove when I move out. (Magnets, child safety locks, etc) Links to specific brands or types are appreciated.

Thank you!
