【Size and Material】This eyeglass case measures 18 x 9 cm, perfectly accommodating most eyeglass frames and sunglasses without excessively restricting the temples. Crafted from PU material, it boasts a smooth and delicate surface. The soft velvet lining securely holds lenses in place, effectively preventing scratches from friction between the lenses and the case, and minimizing damage to lenses and frames from external factors, making it suitable for both travel and daily use. 【Compact and Lightweight】This eyeglass case features a compact design that can be easily opened and closed with one hand, freeing up your hands. Its lightweight design allows it to effortlessly fit into a backpack's side pocket, handbag, or pocket, making it a practical and portable bag for daily outings and travel. 【Waterproof and Moisture-proof】The PU material of the eyeglass case possesses excellent waterproof and moisture-proof properties, effectively protecting glasses from moisture and minor liquid splashes. In daily use, even if water is accidentally spilled on the bag, it will prevent small items such as glasses, lipstick, and headphones from getting wet. In humid environments, it also reduces moisture penetration, safeguarding items from moisture damage, and providing extra protection for small items. [Multifunctional Use] This storage bag is much more than just an eyeglass organizer; it also offers a variety of other storage options. It can serve as a small wallet for coins, a small amount of cash, and bank cards; or as a mini makeup bag for lipsticks, eyeshadows, perfume samples, and other beauty essentials. You can also store small items like Bluetooth headphones, earrings, and USB drives. Organizing these small items in one place eliminates the need to rummage through your bag, making them more convenient and efficient for various everyday situations.
