How the score adds up
Demand and legal risk come from the niche Bulk flexi party favours.
Why it can work
- Seasonal demand: Birthdays year round, Halloween, Christmas
Why it might fail
- Cheap Etsy file bundles of 200 to 1500 flexis were seen at about $1.50 to $3, and such bundles may not carry real rights to the designs
Be aware before you sell
Avoid mega bundles without a clear rights trail, and treat favours as toys for children, including small-part warnings and CE or CPC duties. Cheap Etsy file bundles of 200 to 1500 flexis were seen at about $1.50 to $3, and such bundles may not carry real rights to the designs. Etsy asks for your own original design, so a licensed file may not qualify.
