This black microfiber bag is designed as a Faraday cage to block signals from electronic items you carry daily, such as car key fobs, smartphones, and bank cards. Measuring 13.5 cm by 9.5 cm, its compact size makes it a practical accessory for shielding against unauthorised scanning and reducing exposure to mobile phone radiation. The product is presented with a unisex style and a plain pattern, focusing on functionality for securing magnetic cards and providing a do-not-disturb state for your phone without needing to power it off. It is supplied as a single key anti-theft bag, with available colour options of black and brown.

Features and Construction

This bag's primary function is to create a shielded environment for your electronic possessions using its Faraday cage design. The construction is centred on providing signal blocking for various everyday items, aiming to address concerns around data security and personal exposure.

Material and Build

The bag is made from a black microfiber fabric, which forms the main body of the product. This material gives the bag its structure and is integral to its function as a signal blocker. The design is described as having a plain pattern and is intended for unisex use, keeping the aesthetic simple and focused on practicality rather than decorative style.

Size and Practical Fit

With dimensions of 13.5 cm in length and 9.5 cm in width, the bag offers a compact form factor. This size is intended to accommodate a range of daily electronic items, including smartphones, car key fobs, and bank cards. The scope of application explicitly lists these items, indicating the bag is designed for the typical size profile of such objects, making it a portable shielding solution.

Uses and Placement

The bag is marketed for specific scenarios where signal blocking or radiation reduction is desired. Its applications range from personal security to creating periods of undisturbed leisure, based on the practical benefits outlined in the source material.

Event or Professional Use

For business, public relations, or managerial roles, the bag can be used to block mobile phone signals during meetings or focused work periods without turning the phone off. This avoids potential misunderstandings that can arise from a phone being deliberately switched off. The source notes it allows users to enter a do-not-disturb service state, with callers receiving a 'temporarily unavailable' message, thus maintaining professionalism while controlling accessibility.

Everyday Home Use

In daily life, the bag serves to protect magnetic cards like bank cards and ID cards from degaussing and information theft. By placing these cards inside, the bag shields them from any scanning attempts. It is also highlighted as a product favoured by pregnant users for its aim to reduce mobile phone radiation exposure, positioning it as a item for personal and family health consideration within the home environment.
