CFX, Concept Flex is a flexible memory metal collection.

This collection offers a lightweight, better fitting frame that's comfortable yet durable. Small accidents that can cause standard frames to bend or break won't faze CFX because it automatically springs back to shape.The styling ranges from classic to modern to sporty and is coupled with Charmant's attention to detail and unsurpassed quality. Designed for men, women and children.

The CFX Concept Flex Eyeglasses Eyewear collection provides male consumers with choice eyewear that offers true
satisfaction. By featuring a refined, contemporary design combined with comfort due to this unique metal, it offers eyewear that suits the active and smart lifestyle of today's demanding men.

The metal frames have memory metal, which consists of 49% titanium and 51% nickel and is used in the bridge and temples of the frames. This composition makes it very flexible and allows the frame to revert back to its original shape after being bent.
