Double lock that's difficult for babies to open Automatically locks when closed Locks cabinet, kitchen, bathroom vanity doors, etc., to prevent children's mischief, unexpected accidents, and injuries. I purchased this but did not use it and have been storing it at home. I will sell it to someone who understands this. Due to the thickness, I may remove it from the package for packing. In that case, I will include the cardboard with the instructions. Thank you.
