Color Full Reflective Yarn is a special type of yarn that comes in two thickness options: 0.25 mm and 0.5 mm. This yarn is unique because it reflects light, making it stand out and easily visible in low-light conditions. Imagine it like a thread that not only has vibrant colors but also has a reflective quality, like the material used in safety vests. The 0.25 mm and 0.5 mm refer to the thickness of the yarn strands. The thinner 0.25 mm version is delicate and suitable for intricate projects, while the 0.5 mm version is slightly thicker, providing a sturdier option for various crafting or textile applications
