You can use MagnaPin on any fabrics you wouldn't dare pierce with a pin, such as satin, leather, suede, linen, silk and even fur. In addition, you can use MagnaPin to attach flowers or brooches to hats or corsages or boutonnieres to fine dresses and suits/tuxedos. When you attend a convention or meeting, bring your MagnaPin so that you don't have to ruin your nice clothing when applying a name tag. Further, keep your pendants and scarves in place using MagnaPin. MagnaPin is a jewelry accessory that is composed of two parts. When you pull MagnaPin out of its package, lightly grip MagnaPin between your first finger and your thumb, and then slide MagnaPin apart. Because of the extraordinary strength of the special MagnaPin magnets, MagnaPin cannot be easily pulled apart, you simply need to slide it apart. Cautions: 1. Some magnets have been known to interfere with a pacemaker or defibrillator. Please contact your doctor before wearing MagnaPin if you wear a pacemaker, defibrillator, or other implanted medical device. 2. Please keep out of reach of small children-not a toy. Small parts could constitute a choking hazard. 3. Keep any magnet away from credit card strips, keys with security system chips, fixed or floppy discs, and watches with small batteries. 4. MagnaPin is nickel-plated, and may cause a skin reaction to persons allergic to nickel.
