These are the only collar extenders worth buying. The button matches the buttons on most good dress shirts very closely, doesn't pinch at all, and offers a bit more room than the metal collar extenders I've tried. I had to deduct a star because I can't buy multipacks of solid whites with white yarn. They sell 3 kid size packs which are all white/white. Can we get this in adult size please? Oh, and pro tip: mind the direction of your quad in hand if you don't want your collar flared. As a right hander, I usually tie my tie from right to left - the FIH knot has the heavier end of the knot on the right side of the collar and the top button/extension remains visible on the left. Tie from left to right = problem solved. The first few times it will be like trying to throw a baseball with your non-dominant hand, but you will learn.
