From the announcement:
Our latest release is dedicated to all Deep Wars fans. The mat design represents a bottom of the ocean in all its glory and picture features high detail visuals approved by divers. Have a look at it at our FB gallery or website. We will ship the mat on 15th of March, until then all preorders receive a -10% discount with a code ‘ocean’ at the checkout window in our webshop. Grab it while it’s… Wet?
