This new type of eyeglass case has a lightweight body with an opening without clasps, giving it a casul impression and a concept of quick and easy use. We recommend attaching a carabiner type ring to the metal eyelet on the upper part of the main body, which can be used conveniently with a strap. The case is made of strong Belgian saddle pull-up cowhide leather, which protects the glasses well without losing its firmness. *The opening has no flap or clasp, so there is a possibility that the glasses may fall out if the bag is moved violently or shaken strongly. Please understand in advance that the way the glasses fit into the case may change depending on the condition of the leather.
