Packing:
Tantalum tubes are wrapped with pearl cotton and then packed in wooden cases. Our reasonable packing method can avoid collision and damage of tantalum tubes during transportation and prevent the impact of external goods on products, so as to ensure the integrity of products in the delivery process after leaving the factory.
