Core Functions and Design Features

1. Classified Storage
   Storage bags usually have multiple compartments, pockets, or grid partitions inside, which can store small items (such as cosmetics, stationery, electronic accessories, etc.) by category. This avoids items being mixed, tangled, or lost, and improves the efficiency of access.

   • For example: Travel storage bags are subdivided into clothing bags, toiletries bags, document bags, etc., keeping the interior of the suitcase neat and orderly; stationery storage bags may have pen slots, note compartments, USB slots, etc.

2. Protecting Items
   Some storage bags are made of wear-resistant, waterproof (such as Oxford cloth, nylon) or shockproof (such as those with sponge interlayers) materials, which can protect the internal items from extrusion, collision, or liquid immersion. They are especially suitable for storing fragile items such as jewelry, camera accessories, and skin care products.

3. Space Saving
   Compactly designed storage bags can be folded or compressed, saving storage space when not in use; when in use, they can "condense" scattered items to reduce the occupied space (such as small storage bags in schoolbags).

4. Portability
   Most storage bags are equipped with handles, lanyards, or foldable designs, making them easy to carry or hang on backpacks and suitcases, suitable for commuting, traveling, business trips, and other scenarios.
