Beautifully present sushi, tapas and other buffet items on these 1/4 gastronorm Olympia natural slate boards. Constructed from natural slate, these boards ooze a rustic and natural charm, giving you the perfect backdrop to present your cheese boards and cold meat platters in a more attractive way. These slate boards have been varnished to make them waterproof and oil repellent, helping you keep them in impeccable condition for an age. This coating also prevents the slate from absorbing odours from foods such as cheese or cured meats, ensuring optimal hygiene when serving. After use, gently wipe down with a mild detergent, avoiding submersion in water.
