Model: SG1088 Product Details: A glasses holder is a functional necklace with a ring attached for hanging glasses or sunglasses. You can adjust the length of the cord depending on the fashion you are coordinating with or the situation at the time. To adjust it, simply slide the knot at the top. By sliding the two knots apart, the length of the cord around your neck will be shortened. The previous model featured a knot on the front, but this model has a more elegant design with gold metal beads and knots as accents. This product uses dyed genuine leather. If rubbed against clothing while damp, color transfer may occur. Please be especially careful on rainy days or when wearing light-colored clothing. As it is natural leather, there will be individual differences in appearance. With repeated use, it will age and change to a deeper color.
