Soil is made from moist absorbing diatomaceous earth, which is found in
the district of Kanazawa in Japan. Since ages this earth is used as a
basis for plastering special buildings like palaces and temples. In 2012 h-
concept started, together with the producer Isurugi from Kanazawa,
using this earth as a basis for design articles for bath- and kitchen use
under the brand name soil. The first product was the bathmat. Currently
the soil collection exists of various attractive lifestyle designs.
Unlike other variants (copies) of this unique moist absorbing material,
soil is a 100% eco-product, pure and guaranteed diatomaceous earth
and not mixed with any other material or colorants.
Tidy started working with h-concept in 2008. The tidy lifestyle articles are
characterized by minimalized design, maximized usability and extreme
high industrial quality, made in Japan. Due to the attractive design you
will not want to store the Tidy products in the cleaning cabinet anymore.
We are proud to present on this web shop our beautiful Japanese design
articles especially for you!
