These models of urns are hand crafted and are made fully out of natural and biodegradable materials, which naturally break down and are returned to nature in coastal areas or in the sea. The urns are made solely out of sand or salt and vegetable binding agents.
 
Salt or sand urns are perfect for depositing in the sea. They are hard and resistant in dry environments, but as soon as they are put underwater they begin to dissolve, and disappear in a matter of minutes.
