The D28 is the largest frame that looks great on both women & men looking for a statement. If you’re looking for a frame design at work or going out at night that says, “These glasses have made it this far…you might not.” these may be what you’re looking for. These will not fold 4 different ways into a square the size of a Starburst. The D28 model is a signature piece. Made of 100% Acetate and cut with exact precision. They have lazer etched “Izquierda” and “Derecha” across the tops so you don’t forget which side is the left, and which side is the right.
