Sinful Reflections watercolors are handmade and free of cadmium, cobalt, lead, and mercury. Every batch of paint is made from premium pigments mulled by hand on a glass slab with a homemade gum arabic binder and poured into pans. Every pan is poured multiple times and dries over two to three weeks. This process creates a very pigmented, creamy, and pure paint that activates beautifully when wet.
