## Customer Reviews

### ⭐⭐⭐⭐⭐ Good Value
*by J***A on 1 February 2024*

Arrived quickly and neat little package. Bought this to replace the broken lock on my outside letterbox.It comes with various size locking levers to fit all different types of locking mechanism. I would say that you would mainly use them on the likes of Lockers that you see in schools Hospitals that kind of thing,filing cabinet,letterbox, if you want to keep the crown jewels safe, I would get something a little bit more substantial haha.The set comes with two keys also. Good value worked ok for me.
