The frames are made of a unique material, TR-90 Grilamid. They bend easily and return to their original shape. Made from hypoallergenic TR-90 Grilamid, they do not irritate the skin. Grilamid is a high-quality, ultra-lightweight, strong, and durable polymer material that provides the frames with lightness, flexibility, heat resistance, a comfortable fit, and a long service life. Grilamid is highly impact-resistant. Only organic dyes are used, offering over 40 different shades. This makes them safe and compatible with human skin. The comfort of TR-90 glasses lies in their light weight and anatomical shape, which create exceptional wearing comfort. A new approach, a fresh perspective, and a rethinking of modern trends and technologies used in the production of eyeglass frames allowed leading specialists to create multicolored frames that are completely different from anything else on the market.
