How to shorten the necklace?

This is a commonly asked question: "How to shorten the necklace as it looks different from my country one?" 

Yes, the direction of the clasp may vary in each country. Just simply put the small loop into Clasp, it's done!

For the slider type, just simple drag the slide ball to the desire length, it might need a bit more force for the first time as it is new!
