As with all UV2 dubbings, these have a mix of primary colors that have been enhanced with UV Florescence and UV Reflectence dyes. Each dubbing will kick out a host of color spectrums. Check them out in direct sunlight.
It is best to always use a pearl or silver Mylar under base or even basic white thread which will bounce any light back out of the pattern at a different wave length.
Uses a double dye process to give all UV2 materials and flies the added UVF/UVR ultraviolet wave lengths.
