| Bottles come in many shapes and sizes, colors | | | | utilizing an array of techniques, and material |
| and dimensions. One of the most common ones | | | | selections depend upon relevance. High Density |

| plastic, it normally has a tapered neck, a wider | | | | extensively employed resin for plastic bottles. This |
