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 and doesn't have a bag, but it's unused. The color is black. This is used to prevent eyeglasses from slipping by inserting it into the temples of the glasses. Please refer to the images for compatible glasses sizes. I plan to ship from the post office.
