For most collectibles we recommend dusting with a soft cloth, a small makeup brush, or using spray designed for computer keyboards, which emits puffs of air to remove dust particles from small spaces. Porcelain items may be cleaned with a mild soap-and-water solution, then rinsed in clear water and dried by hand. However, if they are decorated with simulated jewels, fabric or leather, they should be hand dusted only. Limited-edition collector plates are for display purposes only. They should never be used for serving food because of the rare metallic pigments fired into the plates for color fidelity. Limited-edition collector plates are for display purposes only.

Avoid placing your collectibles in direct sunlight for long periods of time, and always handle them with care.
