Question 04: Can I buy a set of sample to test quality? Is it okay to ship by sea or by air? What cost will be?
OKPRO strongly recommend you to buy some samples to test quality before order.This can help you to be confident with OKPRO quality.We are sure that you will definitely love OKPRO products after using them.Most of our customers like to purchase whole sets of sample as they believe its easy to test quality,we do suggest you buying only one pair of 10kg or 15kg for quality testing as whole sets are too heavy and too expensive for air shipping.You may have question that why not use ocean shipping for whole sets of sample?
Shipping by sea for small quantity is also very expensive as you need to pay import duty,handle cost,document cost etc,the total cost will be equivalent to the air shipping while its more complicated and wasting time as well.The air shipping cost per kg is approximately between 8USD and 10USD varying from different countries.
