4.Package & Delivery
package:
Wrap the niobium target material with pearl cotton and put it in a
wooden box. Our reasonable packaging method can avoid the niobium
target materials from colliding with each other during
transportation, and can also prevent the impact of external goods
on the product, and ensure that the product is delivered after
delivery Integrity.
---1. The sealed packaging,then put in the Carton cas or standard
standard plywood case.
---2.Using exclusive custom carton with customer logo, each individual
packaging, to help buyers direct sales.
---Accept customer requirment
Make sure that each package is tailor-made for you.ensure when you get the goods no damaged.
