You know when you\'re colouring in and your pen runs out? These glasses look a bit like that. The two-tone blue of the unisex NK7217 is darker at the top, gradually fading to a lighter hue at the bottom. The top defines your features, while the bottom stops them from being too clunky. They\'ve got a rectangular plastic full frame with a thin metal arm. Again in blue. And a thicker curved earpiece in, you guessed it, more of that gorgeous blue. Cool tones work well for those with a warmer complexion. Modern and distinctive, these are a great choice if you want to dip your toe into the world of two-tone glasses. Subtle but totally on trend.
