## Common ground
All options are containers designed to hold pins, regardless of material.
## Options at a glance
**3926.10 – Made of plastic material**
- **Defining trait:** Constructed primarily from plastic, offering lightweight and corrosion-resistant properties.
- **Typical examples:** Plastic pin storage boxes, small transparent pin trays, craft supply organizers.
- **Best fit when:** The container is lightweight, non-metallic, and likely used for crafts, sewing, or office storage.
**7326 – Made of iron or steel**
- **Defining trait:** Constructed from ferrous metal, providing durability and strength but higher weight and potential for rust.
- **Typical examples:** Heavy-duty industrial pin holders, workshop toolboxes with pin compartments, metal storage tins.
- **Best fit when:** The container is metallic, robust, and intended for industrial or mechanical use.

## How to choose
- Is the container made of plastic? → 3926.10
- Is it made of metal, especially iron or steel? → 7326
## Overlaps & pitfalls
A container could theoretically be made of both materials (e.g., a steel frame with plastic inserts), but the primary material determines classification. If unclear, prioritize the dominant material. No option is vague—both are clearly defined by material type
