Which mode of transport is recommended?

Since production items are generally heavy, we advise delivery by sea. However, we respect your views and can accommodate other transportation methods as well.

What if I cannot find the product I need on your website?

You can send pictures, photos, or drawings of the products you need by email. We will check if we have them. If not, we can develop new models specifically for you based on samples sent via DHL/TNT.
