• Lighting duration - After charging, the thread will continue to glow in the dark for over 3 hours.
• Eco-friendly material - The thread is made from environmentally friendly materials and is safe for the skin and health.
• Pack of 5 popular colors - Includes 5 different colors: pink, blue, yellow, white, and green. Each spool contains 150 yards. The thickness of the thread is approximately 150D, slightly thicker than regular polyester thread (120D).
• Usage tips - It is recommended to use a #14 needle with this luminous thread to avoid possible breakage during sewing machine use.
