Redefine the limits of optical endurance with the KOCOLIOR 256883. Engineered for the high-performance professional, this Full-Rim Polygon chassis utilizes a state-of-the-art Fusion of Pure Titanium and Ultem (PEI) Polymer. Ultem is a high-strength thermoplastic used in aerospace and medical technology, prized for its extreme heat resistance and incredible "snap-back" flexibility. When paired with a titanium core, it creates a frame that is virtually indestructible yet remains featherlight, providing a "zero-fatigue" experience through a 12-hour workday.
The 256883 is a masterclass in Structural Resilience. The technical patchwork construction isn't just an aesthetic choice; it provides strategic zones of high-tensile strength and flexible memory. The titanium provides the rigid foundation necessary to prevent lens warping and optical distortion, while the Ultem outer shell offers a soft-touch, hypoallergenic surface that is immune to the corrosive effects of sweat and UV exposure. This makes the 256883 the premier choice for men who prioritize geometric style and high-tech durability.
The 256883 is meticulously scaled with a 145mm frame width, providing a "Grand-Profile" presence specifically designed for broader facial geometries. The unique synergy of titanium and Ultem allows for ultra-slim, streamlined temples that distribute weight with anatomical precision. This results in a stable, "Zero-Pressure" anatomical fit that contours to the head without the pinching or sliding common in traditional optical frames, ensuring your optics remain perfectly aligned during intensive professional use.

Real numbers, not promises — how long your order takes from the moment you place it to the moment it reaches your door.
Updated · August 8, 2026From the moment you place your order to the moment it is delivered, United States:
This is the complete window, lens making and shipping included — not just the shipping part. Ready-made frames without prescription lenses land at the short end of the range; prescription and custom lenses at the long end.
The window above is made of two parts. Making your glasses comes first, shipping second.
Add the two parts and you get the window at the top: ready-made frames 6 to 14 business days, prescription lenses 12 to 18 business days. Orders placed on a Saturday, Sunday or a public holiday start the next working day, which adds one.
Business days in transit after your order leaves us. Add the making time above to get the full window.
We may adjust these windows at any time without notice.
