Porcelain jewelry is fragile, but with special care, can have a nice long life. Store your pieces in the box provided and separately from other jewelry that may scratch or mark the surface. Be careful when taking them on and off, especially over hard floors like concrete and tile.
Most of the pieces are unglazed porcelain so they have that nice matte finish and texture. Always try to handle them with clean hands. If your jewelry becomes slightly dirty (from handling or makeup), it is easy to clean. Use some mild dish soap and water and gently scrub with a toothbrush.
When traveling, wrap each piece separately in their box, and if possible, carry with you. Avoid pressure from being packed between clothing or other items.
