Fluorescent thread - This fluorescent thread requires sunlight or a light source to "charge" it. Place it in the sun for about 20 minutes or use a light source. Then, you can transfer it to a completely dark place to observe its glow.

Light duration - After charging, the fluorescent thread will continue to glow in the dark for over 3 hours.

Eco-friendly material - Made from eco-friendly materials, suitable for embroidery on bags, clothing, pillows, and other fabrics without affecting health.

Pack of 6 popular colors - The package contains 6 different colors. Each spool has a length of 1000 meters and the thread thickness is approximately 150D, slightly thicker than standard polyester thread (120D). It also includes some mesh threads as a gift.

Usage tips - For best results with the fluorescent thread, prefer using needle #14 when using embroidery machines. If you typically use needles #9 or #11 with polyester threads, a larger needle is preferred to prevent thread breakage during work.
