Chrome Cherry Adhesive Placket Stays CollarLift, To Hold Up Shirt Collars, Discrete & Disposable Shirt Accessory, For A Sharp Look & Bold Hold, No Messy Or Floppy Collar Strips

I actually used these, cut down, with fabric glue, to stiffen up a floppy front of the blouse, below the collar, area and they worked well.

Avoid! The principle is sound but considering that these are supposed to be reusable is unrealistic. When using, it doesn't take long for them to start braking up leaving you with sharp plastic digging into your chest.

Great quality and highly recommended. It delivered as promised and exceeded my expectations.

Not great. They stick well but not strong enough to hold the collar up. Also they are visible from the front and look ridiculous

I recently grabbed these collar stays as an alternative to the chintzy plastic ones that come with my shirts. I've been meaning to get real (e.g., metal) collar stays for some time, but have been lazy about it and thought this was a good option. I'm terrible at keeping the plastic ones that come with most shirts in place; so, inevitably my collars get warped or curl. The idea behind these is that you basically adhere a piece of cardstock inside the collar to keep them flat. Fine idea in principle but not really well executed. The problem is the thickness of the cardstock (or lack thereof). The stock amounts to a thicker stock paper, but not really cardboard. If you have stiff collars that have curled, these adhesive collar stays aren't going to get the job done. It's not all bad. You do get a ton of these in the package; so, maybe there's a case for doubling-up, but I didn't try it. And they're easy to apply and in my experience held all day. Finally, there's a bit expensive. For a little bit more effort you could have a nice pack of metal collar stays and not have to mess around with this stuff.
