These Polaroid eyeglasses are designed for boys between 4 and 6 years old. The rectangular front in eco-polyamide features adjustable rubber nose pads for no-slip grip. The soft rubber-coated temples conceal a Memory Metal core, a material that always springs back to its original shape, even if folded or bent. This style can be completed by an elastic strap, purchased separately. The ‘Sustainable Choice’ inscription attests to Polaroid's green commitment.
