Please pack loose articles separately and securely in bubble wrap so that they cannot bang around and hit the instrument.
If you are shipping inside a case, keep in mind that if the instrument can move around at all, it may become damaged. However, don’t wrap so tightly that the instrument is compressed. A snug fit that impairs movement will be fine! Check all latches to ensure they will not accidentally pop open during shipping.
If you are shipping an instrument without a case, wrap it at least three times with bubble wrap, and secure the wrap with shipping tape. There should not be any edges sticking out. The instrument should be completely covered.
Select a strong and sturdy double corrugated box that offers at least 2 inches of space all around the item that you want to ship. Fill that extra space around the instrument with bubble wrap, crushed packing paper, or packing peanuts.
