Out of stock label

Hi, is there a label for out of stock, as there is for sale (blue SALE label)?

I don’t see any label neither in overview nor in product view images.
I have enabled the WOO Stickers by Webline plugin for now, as my client urgently needed it, but I would prefer not to use plugins for things that can be done another way.

You can test the product with 15998 SKU
