Triple O Glass Cord - Black 5500 yen Size: 700mm Weight: 6g Material: Cupro 000 (Triple O) is a brand that creates accessories using a unique technique called three-dimensional embroidery, which involves layering threads to create spheres. This is a lightweight glass cord, weighing only 6g, that won't feel heavy even after long hours of wear. By hanging your eyewear around your neck, you can easily put it on and take it off, and it also helps prevent you from misplacing them. The cord length is a slightly shorter 70cm. Even when you take off your glasses while sitting, they are less likely to hit the desk, making it an easy-to-use length. The fasteners use silicone rubber, allowing them to be attached to the temples of most glasses. It can be used with various types of glasses, such as reading glasses, bifocals, and sunglasses, making it a great gift. The cord near the glasses has small beads, so it's less noticeable around the face while wearing it. Also, the ivory and wood beige colors use lame thread, which sparkles when light hits it. The main body is made of thread, so even those who don't like accessories or have metal allergies can wear it with ease.
