Question 1

Are these magnetic? If so, which magnets do you recommend?

Accepted Answer

I originally purchased the 1/4" diameter 1/16" thickness neomydium magnets based on someone else's recommendation. Although they did stick and hold, and were quite discrete at that size, they didn't stay on at all. I was literally losing them on daily basis because they would fall off just from the motion of me standing up from a seated position. I did try doubling up with two magnets per collar and the performance improved somewhat but was still disappointing. I decided to try larger magnets and ordered some 3/8" diameter neomydium ones with the same 1/16" thickness. That made all the difference in the world! They still are not bulky and noticeable inside the collar and now they stay on all day and usually even when I haphazardly undress in the evening and forget to take them off first, I find that they stick and are still there in the morning. Highly recommend the larger diameter.

Question 2

Will these stays work with the N48 neodymium magnets ? There is a mention in the description highlighting that the updated version does not !

Accepted Answer

While I don't know what the N48 is, the ones I purchased are Definitely attracted to my neodymium magnet! My stays are the 2 length 2.5 & 2.75, 18 each.

Question 3

how do I know how long my collar stay should be, is there somewhere on the shirt that tells me or should I just pull out a ruler and measure it?

Accepted Answer

A 2.5 inch collar stay is one of the most common sizes.  These collar stays will fit in almost every shirt, and fill the area for the collar stays completely. You can always measure that little area with a ruler or get a package of multi sized stays but if you opt for the 2.5 inch package, they should work with all of your shirts.
