How to use the bathtub rotary plug?

1. First put the rotary plug at the drain below the bathtub, and then press the button to unlock the rotary plug.

2. Secondly, the top of the rotary plug will jump out. You can pick up the middle part of the rotary plug, unfold it and put it back into the drain.

3. Finally, when drainage is needed, you can gently pull up the middle part of the rotary plug and rotate it for a certain angle, so that the water can flow out of the drain smoothly. When it is no longer necessary to block the drain, you can gently rotate the rotary plug and press it down to restore it to its original state, and then take it out and wipe it clean.
