Hello, I'm MrOllie. I wanted to let you know that one or more of your recent contributions have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. MrOllie (talk) 13:17, 21 August 2023 (UTC)

Please do not add promotional material to Wikipedia. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not a vehicle for soapboxing, advertising or promotion. Thank you. MrOllie (talk) 13:19, 21 August 2023 (UTC)


 * Dear MrOllie,
 * Thank you for your feedback and guidance. I apologize for any confusion caused by the previous addition. The intention was to provide general information about the development of artificial leather and offer readers a broader understanding of the different materials available in the field.
 * I understand that the points regarding leatherette and cork leather may appear similar in nature. Leatherette is indeed another type of artificial leather created by covering a fabric base with a layer of plastic, typically polyvinyl chloride (PVC). It has been commonly used in bookbinding and was also frequently found on the casings of cameras during the 20th century.
 * Similarly, cork leather serves as a natural-fiber alternative to traditional leather. It is derived from the compressed bark of cork oak trees, employing a manufacturing process similar to that of Presstoff.
 * I will ensure that future contributions adhere to Wikipedia's policies and guidelines, and I appreciate your attention and guidance in this matter.
 * Thank you once again for your feedback.
 * Sincerely, Siu ming hui (talk) 13:28, 21 August 2023 (UTC)
