Stash boxes with magnetic lids are useful for preventing your cannabis from unknowingly getting falling into your bag or getting lost in the ether. However, magnets may not be enough for keeping children and toddlers from finding your private plant matter.  If you’re a parent, some may recommend purchasing a stash box with a combo lock. Depending on how secure you’d like to keep your stash, some wood stash boxes may fasten with an old-fashioned combo lock. No matter if you trust your children, a lock may be worth the peace of mind. But if you’re likely to forget the combination, it’s probably better to opt for a stash box without a combo lock.
