We use no excessive polishing agents or oils, and polish only with a whetstone. The finish is safe for pets. While not a mirror-like polish, we hope you appreciate the natural patterns of the marble. This serpentine marble offers a variety of patterns even within the same stone type. We encourage you to choose your favorite pattern. Beyond cool mats, natural marble holds endless possibilities depending on the buyer's imagination. Arranging them will surely impress you with their beauty. Measurements are taken with care, but please allow for slight dimensional variations. I also offer cool granite mats. They have a firmness and a sense of luxury that is appealing. However, marble excels in heat dissipation compared to granite, providing consistent cooling, making it perfect for pet heatstroke prevention. It's understandable why some shops make ice on marble surfaces, but there are also disadvantages. Marble is not as hard as granite. It won't easily break unless you force it, but please handle it with care. Also, the crack patterns are a characteristic of marble. We inspect all items by tapping them firmly with our palms, but please use them on a flat surface. The product may have some scratches, small chips, and minor cracks inherent to natural marble. Please understand.
