These reusable sealed zipper bags are designed for secure and discreet storage of jewelry, small samples, and sensitive items. Crafted from non-transparent black mylar, they effectively conceal contents while protecting them from light exposure. The resealable zipper ensures a tight seal that can be reused multiple times, preventing odor leakage and keeping items fresh. The compact 3 x 4 inch size makes them ideal for small product samples, feminine hygiene disposables, or jewelry storage. Their dark black exterior adds privacy and disguises the contents, making them suitable for various personal or commercial needs. Sold in a convenient bulk pack of 100 bags, these resealable pouches are perfect for small business packaging, jewelry organization, or personal use.
