How the score adds up
Demand and legal risk come from the niche Mystery flexi packs. An idea to test can score 69 at most until someone has seen it for sale.
Why it can work
- Few sellers compared with other products
- Seasonal demand: Christmas stocking fillers
Why it might fail
- Under $2 estimated profit per print hour
- Blind packs mix many files, so one unlicensed design can trigger a claim on the listing
- Thin public evidence, so treat these numbers with care
Be aware before you sell
Every design in the pool needs its own commercial right, and Etsy's original-design rule applies to each one. Blind packs mix many files, so one unlicensed design can trigger a claim on the listing. Etsy asks for your own original design, so a licensed file may not qualify.
