[Anti-slip & Better ventilation]: The board and the plastic base are fixed by nails; the surface of the tiles has anti-skid lines to avoid sliding. Also, the PVC plastic base rises up the wood and allows for adequate drainage and ventilation. [Easy to use]: You just snap these fir wood pieces together and place them wherever you want, or detach the tiles for cleaning and storing. The tiles can be cut if you need to fit it around a corner or a pole. [Tight connection]: Each fir wood plank is securely attached to the plastic base with tapping screws, which better makes the wood and base connected more tightly to avoid cracking, and extend the service life. [Low-maintenance]：You won’t have to worry about staining or finishing interlocking flooring tiles before you install them.
