How the score adds up
Demand and legal risk come from the niche Flexi keychains.
Why it can work
- Seasonal demand: Christmas stocking fillers
Why it might fail
- Character keychains circulate, such as a fan Toothless flexi on Printables, and those need a licence from the rights holder
Be aware before you sell
Paid keychain files have their own terms, so confirm commercial rights per file and check Etsy's original-design rule. Character keychains circulate, such as a fan Toothless flexi on Printables, and those need a licence from the rights holder. Etsy asks for your own original design, so a licensed file may not qualify.
