A set of a metal cylinder lock and mounting hardware. Attach it to the glass doors of your cabinets to prevent children from opening them and dropping dishes. Made of metal, it is strong and boasts high safety and durability. There are two keys so that the lock cannot be unlocked due to lost keys. It is also perfect for use on pet cages! Especially for reptile pets, if the cage is not closed properly, there is a risk of escape through gaps. This was included when I purchased the cage. I kept it unused because I continued to use the one I already had. Please only purchase if you do not mind that it has been stored at home. Thank you.
