how many come in the package?

Hi there, thank you for reaching out! Two fins come in the package.

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

Can I use these rears with the front fins of my reator thruster fin set?

Yes they are the rear 2 fins that will convert your tri fin set up to a quad.

Good 👍

Good fins. At first, I was worried since it is too upright, but now, since it's a quad, it's not an issue Alon avisar

Speed

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