[Light, thin and easy to carry] Take it anywhere, only 50g. Not only is it light, but it is also thin at 0.5 cm, so it can be quickly stored in a mini pouch or mini bag. [With D-can to prevent falling] If you attach a reel strap (sold separately) to the D-can, you can attach it to the handle of your bag and prevent the glasses from falling. [Eco-friendly leather] Because it is a vegetable-tanned shrink leather specification, it is not only environmentally friendly, but also naturally fits in your hand. Moreover, it is scratch-resistant, so you can enjoy it in new condition for a long time. Even if you are busy, you don't need to take care of it every day. [5 colors supported] Soft nuanced colors such as greige, smart black, and retro camel. We have prepared a wide variety of colors, from popular dull colors to standard colors.
