Hey @tomas20 ,
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!
Don’t find a sticker that meets your need, reach out to us on chat for a custom design! We also create stickers in various languages.
Hope this helps :) Do let me know if you need any help.
