Cling On was developed to finally resolve the on-going problem of trying to keep pins and scissors within easy reach. Sewers have always found a variety of ways to keep track of pins - the most popular methods seem to be in the mouth or pinned to the shirt. Scissors are more difficult to deal with so they have been hung around the neck or attached to a cord then pinned to the shirt.
We ultimately came up with the concept of using a magnet encased in high-impact plastic that is strong enough to hold small tools and still be light enough to wear comfortably. Attaching it to clothing with a second magnet inside prevents damage to clothing and keeps the holder securely in place.
Of course, it had to be pretty.
