Other types of VCB we can offer:

 

We usually offer export carton boxes or wooden boxes.

 

 

We can arrange the following shipping:

sea shipping, which is economic but slow.

air shipping, which is more expensive than sea shipping but much faster

express. which is fast and suitable for samples shipping.

we can supply paid samples for test.   

If any problems resulted from quality and mal-manufacturing, our after-sales service will help you solve these problems.

We will help you with technical problems during installation and marketing.
