I've been using these tiedowns for years. Literally. In fact, I use them so much they end up wearing out or, which is often the case, I lose them in hotel rooms, the car, the airport. You get the idea (they are clear plastic!).

Not only do my ties stay nice -- no tie tacks or clips to mess them up -- these tiedowns are invisible to other people. I'm pondering giving them as gifts to my office-mates this year.

Highly recommended.
