Displaying SKUs

[KieranC]

Hi all,

I sell a range of niche electrical goods on my Shopify store which are easiest to identify by SKU. Every single one of my products gets assigned an SKU before being made active.

I'm currently using the Focal theme.

I would like the ability to display the SKU on the product page so customers can confirm the product - how would I go about this? 

Thanks in advance!
