The Cellairis CyberSystem Cyber Pouch is a signal-blocking pouch for places that need quiet, focused or secure time away from devices. Once a device is secured inside, the pouch blocks all incoming and outgoing communications, creating a complete signal blackout. The device cannot be reached or detected by external networks while it stays inside. Cellairis designed it for schools and classrooms, and it also suits meeting rooms, exam halls and any setting where phones should stay silent. The pouch fits all major cell phone brands and models, with or without a phone case. It also holds earbuds and smartwatches, so one pouch can hold a person's everyday devices. Water-repellent, tear-resistant materials are built for long-term daily handling. A super-strong Velcro closure keeps the pouch sealed and adds drop protection. For organizations issuing pouches to many people, a transparent ID holder takes a name card or ID card so each pouch is easy to identify. A carabiner attachment point allows hands-free carry. Cellairis also offers custom logo options.
