Put the base tack in the bulletin board or wall first, place your item to be hung over the inserted tack, then use the provided coupling magnet to hang your item in place! Such a simple and great idea. Makes a great gift for a new apartment. Easy way to stop putting holes in pictures or posters and also you don't have to use tape and risk ripping anything. It is way cheaper than any other comparable product on the market! I highly recommend checking it out.
