BIRCH's adjustable neck strap features rubber end loops that fasten securely to frame temples and a slider for easy size adjustment. Keep your sunglasses secure and safe around your neck during all your daily activities.This adjustable strap will fit into glasses with tip thickness of 0.8 mm or less. Please make sure to measure the tip of your glasses before making the purchase. If the rubber tip is difficult to fit into the glasses, apply heat by using hair dryer into the rubber strap to make it softer, so it will be easier to fit into the glasses.
