Clip sunglass cases are typically made from faux (PU) leather, polyurethane, and various plastics, according to product listings.
They attach using visor clips designed for car sun visors, swivel-snap clips, or carabiner loops for clipping to backpacks, belts, or straps.
Common closures include zippers, snap closures, and panel-style covers that fold or snap closed to secure the temples.
Interiors typically feature soft linings, plush or foam padding, and cushioned inserts to prevent scratches and help resist crushing during travel.
Visor-style cases most commonly list two clips or two snap clips to secure the case to a car sun visor; several product descriptions specifically mention two included clips.
Hardshell and firm zipper-enclosed cases—often described as weather-resistant—combined with cushioned foam or soft linings provide the best protection against crushing and the elements.
