A lot of Kadas have the pull and push mechanism. And over a period of time you may notice that it does not close as snug / tight as before. And it opens up by itself.
All you need is a simple nail filer to widen the gap of the lock mechanism in order to fix it and to make sure it works as fine as before.
Incase you have a kada with this lock mechanism and it does not close right, try this out and leave a comment below whether it worked for you or not.
These are simple techniques all silver lovers can adopt to maintain their pieces.
