For badges in description instead of using app there is one more option you can use. You can apply tags to the products and accordingly you can show the badges conditionally.
Hi @angelco ,
I'm new to the Shopify community, and I came across your question on adding a custom badge in your product catalogs. We have developed an app (Modemagic) that will allow you to add product stickers/badges on your catalog within seconds. Check out this app on Shopify here. We have an extensive collection of stickers/badges suiting to any need. No complex edits, no back & forth with designers. Update your store within a few minutes!
Hope this helps :) Do let me know if you need any help.
