Increase the collar size and life of your favorite dress shirts
These Collar extenders work great. I have a bunch of dress shirts size 32/33 with 17 inch necks. The shirts fit great the only problem is that my neck is no longer 17 inches, it is probably closer to 18. I had a job interview coming up and needed to find a way to wear one of my existing shirts. Finding shirts in a 32/33 with 18 inch neck is almost impossible and did not make sense since the shirts I own are in great condition. I took a chance on these and am so glad I did. I attached one to my top button, put the shirt on, buttoned the collar and put on my tie. perfect fit and you could not tell i was wearing a extender.

Excellent product!
I bought an elegant fit dress shirt for my father and wanted to make sure he could wear it with a tie without feeling tight at the collar. This elegant collar extender did a perfect job! I didn't know he already had a collar extender but I was told that the collar extender he had was pinching his Adam's apple and couldn't use it at all, while this new one gives him a real confort and is very elegant. My gift was very much appreciated. I recommend it!

I do like them and they seem like quality items after a week of use, however, at $15 they are pricey for 2 buttons, one of which I've lost already. Not a product defect, rather user error. I'd buy again if they were less expensive.

Works as expected
These things work well and not only do they extend your collar, but they make it expandable due to the elastic. When you turn your head your collar has a bit of give which makes it comfortable in multiple positions. Would have given 5 stars, but I think these things cost too much compared to what you get. I have not tried these more than once or twice so I don't know how they hold up over time.

Mixed feelings, they are good, look good but are pricey
I gave these collar extenders 3 stars and not 4 because I think that they are very pricey. The buttons are really well made, high quality and good looking but not worth the price tag of $14.95 for two. I am sorry, I am not cheap, I like quality items but the makers of these collar extenders really went too far high with the price (considering it will be invisible behind a tie and serve no other purpose). Also, I do not know how durable will the elastic be under everyday use. The metal spring extenders that I own (which are way cheaper) have been doing a great job hanging in there, let's see how these perform under the same use. Other than the price, the extenders are the best looking in the market but with a big $$$. I will love to see these for/under $10.00 which is a more reasonable price.

Awesome Extender
Oh wow! This is the best extender I've seen since I have been wearing them. It's concept is great and the design works very well. I thought the metal extenders were great but this knocks it out. The extension part is elastic and contracts back not to its original position, but close enough. It also has an elegant look to it. It was easy to get on and it does not come off. Best extenders I've seen. Totally worth the money.

Great product. 100% recommended.
I was tired of buying other products that were annoying or broke very quickly. I was surprised by the presentation of the product, the comfort and the quality. 100% recommended.

Great idea. Excellent for shirts that are too tight to button up.

Très pratique
Pour les cous plus larges, c'est parfait. Ça ajoute beaucoup de confort. Le seul point négatif... c'est cher pour ce qu'on a. Par contre, il s'agit quand même d'un bien meilleur prix qu'en magasin.
