Our waterproof concrete is hand casted in small batch and reinforced with steel for extra strength. Each piece is hand-sanded and finished with additional waterproof sealer. We apply copper, silver, or gold leaf pigment for a minimal and contemporary look. Each piece of concrete is truly unique with its own unpredictable pattern and bubbles. We also love the contrast between rough concrete and polished metallic finish. They are perfect as gender-neutral gifts and lovely for all ages.
