A product's various attributes can be modified by navigating to your Product Catalog under Settings > Warehouse > Products. Use the search bars to filter for the product you'd like to change, and click on the right side to enter the Product Edit screen. Modify fields seen here, and save your changes.
You can also modify product attributes for multiple products at a time by using the Bulk Edit feature, detailed in this short article.
