Prepare shipping according to the item, not with a generic method
Before handing the parcel to the carrier, verify that the packaging is suitable for the specific item.
Guitars, amplifiers, synths, cymbals, rack equipment and electronic devices have different weak points. Secure or protect parts that may move and avoid empty space that allows the item to shift freely inside the package.
Also check weight, dimensions, label and the agreed delivery method.
This guide identifies the required checkpoint in the sales process; materials, double boxing, protection and specific procedures belong in the dedicated Muviber musical instrument shipping guide.
