Product sourcing Japan - Gel pens

I am looking for a sourcing and shipping agent to acquire a specific brand or goods from a manufacturer based in Japan, to ship to UK mainland via DDP air.

I will share specific details of the product with the right person or agency.

Product is a gel pen set and i want to understand the total price list and cost.

This is not for a huge order as it is for a new wholesale launch.

Please message me if you are based in Japan and have good experience.
