For the people who got their rotary key

How did you fit the key onto the key ring?

Since it is really hard to fit it into the centre hole of the key because the key are too thick, and there will be a possibility that you will scrutch the key.

And for the hole on the side, it is quite small, you must use something which is really thin, then there will be possibility that you will loose your key because it break since it is too thin.

So, how's fit your rotary key??
