●Cool pins are just that - COOL. They are heat resistant up to 350 degrees Fahrenheit so you can iron over them without melting the tip of the pin or burning your finger. ●The large pinheads are easy to grasp and manipulate - perfect for all ages. And since the tips of the Cool Pins are colorful, they are easy to spot and remove - no pins left behind. ●Cool pins are sharp and fine. At just 1-7/8 inches (.5 mm), they will not leave holes in your finished project. ●50 pins come in a reusable storage box. ●Color: Gypsy Purple.
