It is a brown (cold) to clear (warm) thermal packed full of golden holographic glitters in various sizes. This one will not be fully opaque in a warm or transition state due to the clear shift, however should be opaque in the cold state with 3 coats. Top coat is recommended as this will dry textured.
As with all thermal shades ensure your unit is kept well sealed in a dark location. Thermal transitions slow over time so we always recommend using them sooner rather than later to get the most out of your bottle.
