Important Shipping Information

Shipping items requires specialized, durable packing to ensure your purchase arrives safely and intact. Heavy packages put much greater stress on boxes and packing materials, so using new, heavy-duty boxes and robust cushioning is essential.

We do not use reused abused boxes or low-standard packing materials for heavy auction items. Abused boxes can be weakened from previous use and may fail during shipping.
We use reinforced packaging and strong cushioning to protect your item from impacts and rough handling during transit.
Carriers often apply additional surcharges and may handle heavy packages more roughly, making proper packing even more important.

This is why our shipping fee may seem higher than expected: The cost reflects our commitment to using the best materials and methods to ensure your item arrives in the best possible condition.

Thank you for your understanding and for valuing the care we take in shipping your purchase!
