STEPPER STS 10042 F660 Overview

The STS 10042 features a full-rim rectangular / softly geometric frame shape, giving a clean, professional look that works well for daily use, office wear, and general prescription lenses.

The F660 color code across Stepper STS models is typically a cool grey / smoky blue metallic or matte finish, giving the frame a modern, understated appearance that is neither too dark nor too flashy.

Stepper’s STS line is known for:

Extremely lightweight construction (often under ~10g in similar models)
Flexible temples for pressure-free wear
Even weight distribution across nose and ears
Comfortable fit for long screen time and daily use

These characteristics are consistent across verified STS F660 frames like the STS 10043, which uses a similar design and size structure (around 54–13–135 mm configuration).
