Brand new, never used. Ffern terracotta scent diffusion stone kelp seaside design handmade in Norfolk, England. Ffern x Norfolk Pamments. In our search for a sustainable diffuser for our fragrances, we lighted upon terracotta as a traditionally used material that is kind to the earth - and from there worked with tilemakers Norfolk Pamments to develop our bespoke diffusion stones, handmade from Suffolk clay. Handmade terracotta diffusion stone in light peach pink with embossed kelp seaside design. Ideal for gently releasing fragrance.
