Sack-O-Phones is a unique storage and carry bag that doubles as a knapsack, and this one holds 5 blue Primo™ headphones with a 3.5mm plug. Each Primo™ headphone comes in its own heavy-duty, anti-lice, write-on, moisture-resistant, resealable bag. Prevent The Spread of Lice:
Built with kid's health and safety in mind, each headphone comes in its own heavy-duty, write-on, moisture-resistant, resealable bag. When sealed in the bag, lice are killed in 24-48 hours, without the use of chemicals.
