Tips：

Dear Customer, thank you for choosing our book. To ensure a satisfactory shopping experience, please read the following information carefully before placing your order:

Regarding Size & Weight: There might be a slight tolerance of 1-2 cm / 0.5 inches in the product's dimensions due to different measurement methods. The weight shown is an estimate; the actual weight may vary slightly.

Regarding Color & Cover: Due to monitor color calibration, different printing batches, lighting, and photography angles, the actual item's color may slightly differ from the website images. The cover design may vary if the publisher updates the edition, but the content remains identical.

Regarding Packaging & Shipping: To protect the book from damage during long-distance international shipping, we package it securely in a bubble mailer/bag. However, due to the rigors of transit, the external plastic protective film (wrap) may sometimes get stretched, torn, or come off.

Important Note: This issue is solely to the external plastic film. The internal pages of the book remain completely intact and unaffected, and it does not impact reading or use in any way.
