I love these knobs. The knobs are made with a painted process known as pour painting or fluid art. Several colours of acrylic paint are mixed with a pouring medium, and then the resulting mixture is poured on the knobs. Each knob is unique, and each knob is different. After several days of curing sometimes even a week, each knob is then hand painted with shellac for durability and longevity. Voila knob art.
I stand behind my knobs. If you are not satisfied just let me know. Returns are always welcome.
