[4mm Wide]
100 Meters White Soft Elastic Cord. The brushed texture lends softness for use where the cord may be exposed to skin like face masks. 5mm and 4mm width is perfect for most uses, especially in face masks because it is thick enough to stay put behind the ears (does not slide through). This elastic is made from high durability polyester and covered with spandex yarn. It will not loose shape. Can be washed and stretched as many times as you need.
