These are plastic and metal rectangular shaped folding readers in tortoise frames. The coolest thing about these readers is that they fold in half at nose bridge and the metal arms with telescoping rubber tips fold up so the glasses are half size and fit into a matching color zipper carrying case. These are a must-have for those who need a little help with close ups. Made with integrated nose pads, tortoise frame and 2.25 power polycarbonate lenses provide 100 percent UV400 protection. Measures 28mm tall, 143mm long, and 140mm wide fully extended.
