Hi Pablo and welcome to TilersForums.com
We don't usually allow a company to promote themselves without contributing towards the forum running costs, by sponsoring the forum.
I will let this one link through, and hope you stick around. It will be nice to have some views coming from Spanish suppliers.
Do you manufacture those?
p.s. Your website doesn't load when I put in
https://www.gresmanc - that means it could be insecure, and Google Chrome web browser flashes a big warning up at me. It would be off-putting to some people perhaps. To make it load on https:// instead of just http:// (without the letter S for 'Secure') normally costs nothing to change. It's free.
If you'd like any help with that, give me a shout.
Just a couple of bits I could add to his info already:-
