At first, this rounded marking was thinner and made in celluloid, a species of an acrylic predecessor, which was used until the mid-40s, when it was replaced by high-quality acrylic. Because of its appearance, it was defended for years and by many, that the point was made in ivory. However, that is a widespread legend that lasted for years. We have as evidence, the description of The White Spot in an action that Dunhill advocated the exclusive use of the Spot in 1922. | At first, this rounded marking was thinner and made in celluloid, a species of an acrylic predecessor, which was used until the mid-40s, when it was replaced by high-quality acrylic.

'''Note:''' All pipes come with a costly fitted black ebonite (is generically known as hard rubber and is obtained by vulcanizing natural rubber for prolonged periods. Ebonite may contain from 25% to 80% sulfur and linseed oil. The material has also been called vulcanite, although that name formally refers to the mineral vulcanite). | '''Note:''' All pipes come with a costly fitted black ebonite (is generically known as hard rubber and is obtained by vulcanizing natural rubber for prolonged periods.
