Penofin oils penetrate deep into the wood’s surface, coating the individual fibers. Their stains contain sustainably-sourced Brazilian Rosewood oil, which allows wood to retain flexibility without creating surface film. Penofin oils offer long-lasting shine and beauty, with the typical lifespan being 9-24 months on horizontal surfaces and 2-5 years on vertical surfaces.
