Zoff Smart - Set of 2 Colors: Green Black and Blue Black Material: Plastic Size: 50□15-138 Very light and comfortable to wear. The lens size and shape are the same for both models. My child used these, but they've outgrown them, so I'm selling them. You can replace the lenses at Zoff for a few thousand yen, so please look into lens replacement details. The condition is good, but these are used items, so please understand before purchasing.
