## Questions & Answers

**Q: Is its  a set our just one?**
A: It's a set of two back fins.

**Q: how many come in the package?**
A: Hi there, thank you for reaching out! Two fins come in the package.

**Q: What is the foil?**
A: The fin foil is an aerodynamic shape from front to back of the fin. Much like the wings on an plane, this foil generates lift under the board. A fin is usually going to get thicker through the center of the fin and taper smaller out towards the edges

**Q: Can I use these rears with the front fins of my reator thruster fin set?**
A: Yes they are the rear 2 fins that will convert your tri fin set up to a quad.

*by J***R on Reviewed in the United States on 12 September 2021*

These fins work great! They seemed to add speed and still had enough release on the snaps to slide the tail around.
