Description du produit

These pieces from Zogno require a light by backlight to be able to see the color. If you use a cold light, the color will come out dark blue, or a warm light the color will be dark purple. These specimens also have the particularity of being fluorescent, but by flash fluorescence. That is to say that with long UV, the color will be intense red, but this one will fade little by little to disappear of itself. Just wait a little, then renew the UV to review this red color.
