The SAFE LOCKER 420 is about “RESPONSIBLE STORAGE”. The mainstream use of herbs has resulted in a heightened concern over the possible accidental access by young children, with potentially harmful consequences. In response to this real threat, this storage solution provides multiple levels of childproofing, from the built-in lockable outer case to the childproof caps found in each individual glass jars. Please be aware that this safe storage kit will NOT be an effective deterrent against unauthorized access by older children or adults who maliciously intend to access the contents. The "childproofing" lock is only a deterrent against accidental access by YOUNG children. Assess your personal and home situation accordingly. This case is great for travelling but it is NOT designed to conceal contents on any facility that is expected to inspect luggage and packages. This product contains small items (e.g keys) that can be a potential choking hazard. Keep out of reach by children.
