56 Collar Stays for Men's Dress Shirts - Premium Dress Shirt Collar Inserts, 4 Sizes

I have been using these for a few years now, and they are great, polished soft edges, and different sizes. Perfect.

It has exceeded my expectations with its high quality and superb efficiency. I highly recommend it to anyone looking for solutions to enhance their brilliance, although it is somewhat heavy.

Great pair of stiffs, the are magnet so you can use small magnets to keep them in place.

Great replacement for the plastic collar stays. They don’t rust and are hard enough to keep the collar straight. The down side is that they need to include smaller sizes. Maybe reduce the number but give a bigger size range
