Mater became. Founded in 2006 as one of the first companies in the industry to invest 100% in being sustainable and taking care of "Mother Earth" = Mater.  The ceramic pebbles series was one of the first products in Mater's product range. Since then, products have been taken out of production, as they chose to focus exclusively on furniture and lighting.

I am very proud of the series and would like to see it go back into production... So bid in if you're looking for something like that.
