Folded Arms Set the Depth
A pair of sunglasses can look almost flat from the front while becoming much deeper once the temple arms are folded behind the lenses.
That folded profile should set the starting dimensions for Custom Sunglasses Boxes. If the box is sized only from frame width and lens height, stacked arms can press the eyewear upwards, push against the lid or force the frame to sit at an angle.
The deepest point may come from the temples, hinge hardware, nose pads or curved lenses rather than the visible front of the frame.
Measure the sunglasses exactly as they will sit inside the finished case. The packaging should accommodate that natural folded shape instead of asking the frame to flex into a shallower cavity.
