Ever since it was decided to create a trading company, Ethan buried himself in books and work as he began doing extensive research.
There weren't many things from the earth that Ethan knew of that could be made in Akarxia without hassle. Contrary to what one might expect, it was extremely difficult to manufacture Earth's products in a different world as the availability of ingredients and tools was very tricky in the new world.
Even if that wasn't a problem, there weren't many goods that Ethan knew how to produce in the first place. Ethan was a genius in his previous life but he wasn't all-knowing. The little knowledge he had about how to make a certain few products was solely due to reading books.
But even if this was the case, there were still many options that could work. For example, soap or shampoo.
