Porcelain sculptures are delicate and require meticulous packaging to ensure they arrive intact during transit. The best materials for protecting these fragile items combine cushioning, stability, and shock absorption.

1. Bubble Wrap: A staple for fragile items, bubble wrap provides excellent cushioning. Wrap the sculpture in multiple layers, focusing on protruding or delicate parts.

2. Custom Foam Inserts: For high-value pieces, custom-cut foam inserts snugly hold the sculpture in place, preventing movement inside the box.

3. Packing Peanuts: Lightweight and effective, packing peanuts fill empty spaces in the box, absorbing shocks and preventing shifts.

4. Double-Walled Cardboard Boxes: Use sturdy, double-walled boxes to withstand external pressure. Reinforce corners with extra tape.

5. Air Cushioning Film: Inflatable air pillows offer superior protection by creating a buffer zone around the sculpture.

For added security, label the package as "Fragile" and consider insurance for valuable pieces. By combining these materials, you can significantly reduce the risk of breakage during transit.
