After contacting Merch Support who weren't particularly useful on this matter, I'm hoping @Elizabeth@Amazon or someone similar can advise.
Now we have a whole range of new products, are we allowed to tell customers that the same design is available on other products under the same brand name, and by clicking the brand name, they can view the other products.
I was thinking about putting something like this in one of my bullet points:
This XYZ design is also available on other clothing and products including T-Shirts, Hoodies, Long Sleeved Shirts and Sweatshirts. Click the brand name to view more
Thanks in advance
