Car Safety Belt Extender

Note: This product can be used for models with bolt width of 2.1cm-2.2cm. Most cars are of this size. The bolt width of the original car of a few models is 2.45cm-2.53CM. If the bolt of your vehicle is 2.45cm-2.53CM, please do not take a picture, thank you.
It's better to check the width of the iron sheet of the original car. The size of the original car is more than 2.2CM. The two sizes of the iron sheet of the metal part whose length is less than 3cm can't be used.
