I bought these for my boyfriend based on my brother's recommendation and he absolutely loves them.  I was shocked to see that I was about to pay $40 for 3 sets of collar stays, but I knew it was a gift, he hated the plastic ones that come in shirts and what difference if I spent $40 for three sets, or $40 for six sets; he can only wear one at a time and I was still spending $40.

He loves them, the magnets are the best part because they keep his collar from sticking out and they remain concealed.

Not something he would every buy for himself, but I've told several girlfriends and they have purchased these for their boyfriends and husbands and have made many men happy.
