EasyClip EC517 With Magnetic Clip-On Lens Eyeglasses 。A nice vintage piece from the brand Senator, eyeglass frame with a magnetic clip-on polarized lens. These frames are associated with high-quality, lightweight materials such as ULTEM (a durable, flexible plastic) and metal. The model is Magneto 204, designed for convenience, allowing the user to switch between regular glasses and sunglasses via magnetic attachments. Made in South Korea. The size is 50-18-135. It\'s in brand new, fresh out of the box condition, including a cleaning cloth and pouch for easy storage. These frames have never been worn or had regular lenses installed. The regular lenses are a demo, while the polarized ones are ready to use. They are new/old stock. They can be made to hold your prescription or sunglass lenses at any local optical store, where they can adjust them to fit as best possible. I procured this from a reputable eyeglasses company, which renders this piece is a legit vintage.
