(Just in case you were wondering: "RECTOVULAR" is a word I made up because the shape of this mould is like a cross between "rectangular" and "ovular"!!)
Each soap you make will weigh approx. 113g (4oz).
They will measure approx. 4" x just over 2¼" (100mm x 60mm) and they will be just over ¾" (20mm) deep.
