# Product

Each slab is one unit and one listing.

A listing is complete when it has:

- Inventory photo(s), uniform 3:4 transparent PNG
- SKU, length, thickness, price
- Species, wood category, edge type, figure, grade
- Thickness band, moisture
- One or more `fig-*` tags
- Title, short title, description
- Zero or more `feat-*` tags

Categories, attributes, and `fig-*` / `feat-*` tags are the store filters. Measured values feed title and description templates.
