1. If you have main luggage, initially pack the wands into it. Do not carry them in your hand luggage without the need.
2. In the event that customs officers are interested in the items (as suspicious, for security purposes), calmly explain to them that "these tools are your personal biostimulators made from copper and zinc with quartz fillers inside" (or coal and iron, depending from the purchased type).
3. As a confirmation, do not forget to take the certificate (comes with the «Wands of Ra» kit). It contains the product description, contact information of the manufacturer and the website address. This will help to avoid unnecessary misunderstandings on the part of customs officials.
And...good luck with your trip!
