Dispenser for Knight's castile soap, 'specially made for the face', with four compartments for soap tablets within a revolving tower, made by John Knight Ltd, London, England, c.1930-1940.

Made from wood with glass panels, this soap dispenser may have been used in a pharmacist’s or chemist’s shop to promote and sell the product. It could also have been found in a hotel to enable guests to purchase soap bars.

Knight’s Castile soap was introduced in 1919 by John Knight Limited, now part of Unilever. The original ‘Castile’ soap was made in Castile, Spain, from olive oil and soda.
