商品图片 Nifocc Adjustable Metal Buckles for Chain Strap Bag Handbag Shorten Length Chain Links Tiny Clip for Crossbody Chain Strap Length Shorten Accessories 4 Pcs 2 Colors

I use this to shorten the chain on my Chanel wallet bag and it's perfect. You can use it many ways to create different styles of handles on chain bags

They are not both the same thickness. The silver ones are thinner so easier to go through chain of chanel WOC (unfortunatley mine is gold), the thicker ones go thorugh 2.55. So not sure if you can stipulate on ordering which thickness in the colourway you want.

Looks good, and a great size, but the middle part swivels/rotates to attach your chain or clasps to, but unfortunately there is no lock mechanism, and so this middle part moves far too easily, I can see it accidentally coming open very easily, so not fit for purpose.
