**Lists** are common [visual and non-visual properties](/using-tuplo-studio/product-groups/visual-and-non-visual-properties.md) (like colors and sizes) that differentiate items within a product group. Building a library of these common properties lets you quickly drag and drop them when creating new products.
***
## Why Use Lists?

* **Focus:** Lists emphasize the product distinctions (e.g., color, size), making it easier to find the correct details.
* **Flexibility:** Store Visual (e.g., color) and n]Non-Visual (e.g., size) properties for comprehensive product descriptions.
