The brooches use raw amber to represent the cigarette filter, (alluding to the traditional amber smoking pipes), the amber is initially formed on a grinding machine and then using pendant drill for fine details. Silver is thinly rolled, oxidised and manipulated to emulate burnt or crinkled paper, with the ground waste amber used as tobacco filling. 24k gold is applied referring to the Marlboro Gold cigarette through the technique Keum-boo.
