A certified helmet carries a label inside the shell showing the standard it meets, along with a homologation number that identifies the specific model tested. This label is worth checking on any helmet, since it confirms the exact helmet in your hands passed the test, not just the range it belongs to.

The trade off is scale. A workshop like this will never produce helmets as fast as a large factory, and that is treated as acceptable, since the aim is a considered, well finished helmet rather than the fastest one to market.
This kind of workshop sits closer to a design studio than a factory. Colourways, trims and finishes are developed the way a small run of any crafted object would be, with samples, adjustments and a final sign off before anything reaches a rider.
This is slower than fully automated manufacturing, and that is the point. A handcrafted shell trades speed for a level of finish and individual attention that a purely machine made helmet does not offer.
A leather trimmed helmet needs a little more attention than a plain shell, but the upkeep is straightforward. Dust and light dirt can be wiped away with a soft, dry cloth, and any marks are best treated with a product made for leather rather than general household cleaners, which can dry the material out over time.
