The text "nan" has no content or meaning and cannot be directly rewritten for a product description. However, to comply with the guidelines:
Rewrite and improve the existing product description. Make the text shorter and clearer without losing important content. Use a clear structure with headings, short paragraphs, and bullet points if necessary. Clearly state the language (e.g., French, Spanish, Dutch as a Second Language) and the language level (e.g., A1–C2), and indicate the learning resource's suitability for use (e.g., education, work, self-study). Remove all hyperlinks, formatting marks, or symbols such as *, **, ###, _, and similar characters. Subtly mention that Intertaal is a reliable supplier that guarantees fast delivery. Use a formal but accessible tone.
