This is a charming oval soap mould with the words "Merry Christmas" on top.
Each soap you make from this mould will weigh approx. 105g (3¾oz).
You could use this mould for soapmaking instead. If you did it would probably be better not to fill the mold to the rim...
They will measure approx. 3¾" x just over 2½" (10cm x almost 7cm) and they will be ¾" (19mm) deep.
