What is the ruling on taking and using free samples from cosmetics company representatives designated for the pharmacy company, and what is the ruling on selling them, and is it permissible to request a personal sample from the representative?

It is permissible for workers to take product samples and benefit from them by selling or otherwise, if the company permits them to do so and does not stipulate that they be distributed for free. However, it is not permissible for an employee to request a sample for personal use, because this falls under employee gifts, and the representative only gives samples to companies. It is not permissible for an employee to take them without the permission of their employer.
