Engineered for the younger child, the ET991 Kids eyeglasses (with no clip-on lens) from EasyTwist Kids are impressively durable. The round frames are made in EasyTwist’s proprietary Trilaston memory metal that will bounces back to its original shape after mishaps. The TurboFlex hinges can bend in any direction and will not break. The skull temples curve gently around the head to provide a secure, comfortable fit, and feature a subtle pattern for added appeal. The ET991 from Easytwist Kids makes a smart choice for the active child.
