I love these!! They work great fo my hanging flower pots and you can use them for your humming bird feeders and bird feeders too!!

These are ok.Maybe I got a bad batch, but half of them broke during one day of use. The rest are fine and have been for weeks.

I tried 3 right out of the bag because I couldn't button my 171/2 inch neck collar. All 3 the wire broke. Not woth the buy for me.

These collar extenders have served me well--however, after a few months use, I have had 2-3 break. so not sure how long they will last. Yet, they do well and serve their purpose, making a tight-fitting shirt much more comfortable. I would recommend with the understanding that they will not last too terribly long.

These make wearing a tie far more comfortable. I am a trim/fit guy who wears athletic fit dress shirts; however, the necks are always a little too snug. Getting a shirt with a bigger neck size would mean too much material around the waist.. These are the ideal solution!

I've used collar extenders like these for years: they're handy to have around, because you always have a pinch moment where you need a dress shirt but they're all in the laundry. Using these, you can turn your casual shirts into something you can use a tie with. Or, in my case, the 'slim fit' shirt I bought turned out to be surprisingly slim and I need a little more breathing space.

Great for those tight dress shirts to extend the collar for breathing room.

These could be sized in quarter inch increments, as people’s needs vary. They worked well, but could have been a wee bit bigger.
