Harry Potter's invisibility cloak is a magical item featured in the Harry Potter series by J.K. Rowling. It allows the wearer to become invisible, making it a valuable tool for sneaking around and avoiding detection. The cloak is one of the three Deathly Hallows, which are powerful magical objects in the series. The cloak is unique because it does not wear out or lose its power over time. It was originally created by Death as a gift for Ignotus Peverell, one of the three brothers in the story of the Deathly Hallows. Throughout the series, Harry uses the cloak to help him and his friends in various adventures.
