Show multiple products (urls/pages) on the front-end with dynamic titles/descriptions/meta based on a single product in Craft Commerce
Go to admin panel settings-&gt;routes 
And do something like: 

First * is your product-slug, Second * is your variant unique value, could be SKU or some other custom field you have.



Then in your your-product-detail.twig

   {% set productSlug = craft.app.request.segments()[1] %} 
   {% set variantUniqueValue = craft.app.request.segments()[2] %}


Then based on these two values, do craft variant query to get variant information and display it.
