The Flooring Evolution of Atopic Killer

We avoid using fillers like putty or machine-made plugs and opt for natural cedar branches. It ensures long-term durability. Our Unique drying process allows us to preserve 100% of the wood's natural characteristics. We do not use sander's machine but our surface finish technique akin to the meticulous craftsmanship of a carpenter's hand plane, utilizing ultra-hardened blades. In the final stage, each piece undergoes a thorough quality check, and are handmade corrected using hand planes. Our flooring boasts a subtle sheen, offering a smooth and pleasant feel underfoot, and it's been highly praised for its slip resistance, even when walking barefoot or in stockings."
