Dinosaur Designs homewares are suitable for cold food presentation only. These products should be hand washed in warm water. Resin may appear “frosted” after washing and should be rubbed with a drop of cooking oil to restore sheen. All resin items are strong and durable but should be treated like a ceramic as they can break if dropped or knocked against a hard surface. Resin is not fire resistant and so should not be used in an oven, a microwave, dishwasher or as an ashtray. Like many materials, certain colours in resin may change over time, due to the conditions they are exposed to including sunlight. Resin is a non-porous material. If any cosmetic discolouration or stubborn marks are noticed, we recommend using a mild abrasive cleaner or cream cleanser to assist with removing them.
