Nice,
Just to add, I have some of the more fantasy aligned ones - paving, paving accents wood planking etc, to use with a lot of the fantasy stuff I have queued up.
Thinking another order in the new year, as to be honest although the Basius ones look fantastic, the pricing even with post USA/UK for the happyseppeku ones put them in 'affordable' thing rather than er, not.
And I do like them. They does the job quite nicely.
Not sure if the metal decking/plates and other bits they do are sci-fi are what you are looking for but they are all clearly shown with pressed examples on their website.
