This is a protective measure for both of us. It may, however, subject you to an import tax or duty in your country. Since I cannot be responsible for late, misdirected or lost mail, I suggest you request shipping insurance before you order. Don't panic, I have sent thousands of tubes all around the world. So far, not a single package has been lost or damaged.
Insurance is still a good idea, however.
I pack every order carefully. However, I cannot be responsible for shipping damage on uninsured packages. I normally ship USPS priority mail or UPS for USA orders, and air parcel post for overseas orders. All of these methods of shipment can be insured. E-mail me for a quote.
