03 — About Bizon Covers
BIZON Covers started in 2018 with one obsession: why do protective cases have to be ugly? Founder Marek Bizon — industrial designer and mountain biker — cracked three phones in one season and decided to build the case he couldn't buy.
Today we are 42 designers, engineers and leather craftsmen. We prototype in Warsaw, test in our own drop lab, and produce in small batches to avoid waste. No fast-fashion plastic. No greenwashing. Just honest armor: repairable, recyclable, guaranteed for 2 years.
Our promise: if your BIZON breaks before your phone does — we replace it free. 11,203 replacements so far, zero questions asked.

First silicone bumper sewn in garage. 200 pcs sold to friends.
Stratum launch. 50K units, MIL-STD certified.
Leather atelier opens. Full-grain, vegetable tanned.
480K community. Carbon-neutral shipping, recycle program.
04 — How we build
We 3D-scan every new phone on day one. 0.1mm tolerance for perfect snap, no wobble, no dust traps.
Drop tower, tumble, bend, car-run-over test (yes, with a real SUV). Only survivors go to production.
Leather edges dyed 3x, buttons tuned, MagSafe calibrated. Then 100% hand inspection under light.
