The D28 is the largest frame that looks great on both women & men looking for a statement - at work or going out at night. These will not fold 4 different ways into a square the size of a Starburst. Caddis has admiration for substance, and the D28 model is a signature piece. Made of 100% Acetate and cut with exact precision. Caddis' lazer etched “Izquierda” and “Derecha” across the tops so you don’t forget which side is the left, and which side is the right.
