These items are perfect for keeping your tie from flapping in the breeze or slumping from one side or the other.  They are simple, attractive and inexpensive.  They seem to be tight enough where they slide over the shirt button to stay in place and cause no damage to your ties.  Who wants to punch holes in a $75.00 tie to use a tie pin!!!  I have used these for a number of years and am currently replacing a lost item.
