Megarock V, new and unused. Size: 3.0 x 1.5 x 0.5 (cm) Weight: Approximately 1g Material: Silicone Country of Origin: Japan Included: With adjuster, with dedicated (portable) case I bought this a few years ago but never used it. The other one has been opened once and doesn't have a bag, but it's unused. The color is black. This is inserted into the temples of your glasses to prevent them from slipping. Please refer to the images for compatible glasses sizes. I plan to ship from the post office.
