Perfect

Just as expected! I got these for my husband, and he absolutely loved them. He had no idea elastic extenders were a thing—he’s only ever used metal ones and always complained about them pinching his neck. Not anymore! 😊

The best collar extender I have ever used!

I am so happy with these fancy collar extenders I received from cochic. I used to own the metal cheap ones you can buy from amazon but they would always pinch my neck and also not go with the buttons on my dress shirt. Now not only does the collar extender look exactly like my shirts buttons but it doesn't pinch my skin at all. Shipping was also super quick! Two thumbs up!!

The perfect collar extender!!

I absolutely love my new collar extenders from Cochic!! I have had many problems in the past with cheap metal collar extenders pinching my neck and just not feeling good, but with these they not only look very nice with my white dress shirt buttons but they never pinch my skin! Thanks again!!
