What should I do if the button of the sling is loose?

You can adjust the appropriate length and fix it with a needle or a smaller pin. If the effect is not satisfactory, you can change the front button.

Alternative method:

1. The front of the sling mainly has a gourd buckle and a square buckle. Put the sling into the hole of the square buckle first, and then take it out from below.

2. Thread the belt passing through the square buckle into the gourd buckle, and then pass through the hole in the middle of the gourd buckle.

3. Sweep back the part where the belt passes through the gourd buckle to make it parallel to the belt in front, then turn it over and do the following operations.

4. Pull out a part of the belt at the square buckle to leave room, put the belt at the end in, then take it out from the opposite side and straighten the belt that has just been thrown out.

5. Don't expose the tail of the belt too much, so as not to affect the appearance. Adjust the specific length by yourself. Connect the other half of the button in the same way, buckle it and the sling will be connected.
