The use of certain cutlery/food could cause damage to the graphic. To avoid this, we recommend to avoid using metal cutlery for preparing food and avoid using the bowl/ plate to prepare oily, sugary or acidic food.
For cleaning, always use warm water with mild, non abrasive detergent, then rinse and dry thoroughly. Do not use sourcing pad or dish brush or scrubbers for cleaning.
Ideally, store the bowl/plate in dry and safe place, away from heat and sun light.
