Bundy tubes are vulnerable to direct exposure to sweat, water, heavy moisture, and ocean atmosphere, especially in southern and coastal areas, and in the ocean as well.
Bundy tubes with no plating or original copper plating can rust gradually when exposed to fresh water or heavy moisture. Direct touch with sweat or sea water, or exposure to ocean atmosphere fastens the rust speed and the tubes might turn to total steel scrap if not properly packaged.
The typical package of the Bundy tubes is firstly wrapped in bundles with plastic film inside to avoid any contact with atmosphere, sweat and water; then wrapped with woven strips to have further proof against water and atmosphere, and protect tubes from wearing and foreign contamination.
