Transparent PVC plastic. Lightweight and see-through makes it easy to see which glasses are inside. A pack of 5 cases. Size: 6"x1.8"x1"/15.4cm*4.5cm*2.5cm. The size is enough to keep your glasses and not bulky. Fits your various pairs of glasses perfectly. These cases are available for reading glasses, eyeglasses, and even sunglasses. Snap-button closure. They close easily and remain closed. The clasp is just tight enough to stay shut but allow opening with one hand. The ends and bridge (nose piece) support are hard plastic. The rest of each case is a softer plastic. They'll protect glasses from scratches, drops, and dirt, but not from being crushed. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
