Peace, mercy, and blessings of God be upon you. I am offering you drawer locks for drawers, refrigerators, etc. These locks are of two types: key or secret code. They work without electricity or batteries. They come with very, very, very strong 3M adhesive that does not come off after installation for security. And you can also install them using special screws. You have the freedom to know that they all come attached (adhesive + screws). They are very, very, very excellent for several purposes in any home. Thank youuu
