What is a Princess pillow?

Could you please clarify what exactly is meant by a "Princess pillow"? Is it a type of decorative pillow with a princess theme, or is it a specific brand or model of pillow? Are there any unique features or benefits associated with this pillow that set it apart from other types of pillows on the market? If so, could you elaborate on those features and benefits? Additionally, are there any specific materials or fabrics used in the construction of the Princess pillow that make it stand out? I'm curious to learn more about this product and its potential value in the marketplace.
