We currently have a semi-matte hardcover & use a semi-matte paper for the pages.  Please note that exact thickness of the paper depends on a following things:

• What type of Travel Book was chosen: Lay-flat or Premium Travel Book 
• The number of pages you have in your book.

Our Lay-Flat Premium books use 300 GSM paper, while our Premium Travel Books use between 150 and 200 GSM. To learn more about the two types of Travel Books we offer and the various page thickness, please read here.
