Stack of interlocking vinyl or laminate flooring planks with a realistic wood-grain finish. The main planks shown feature a rich, reddish-brown walnut/teak pattern with prominent grain swirls. They’re long, narrow boards typically used for durable, water-resistant flooring that mimics hardwood. You’ve got a few different shades stacked together — darker walnut, lighter oak, and gray tones — leaning against what looks like a workshop or store entrance.
