Each box comes with 16 strips that are split into 2 packets of 8. I was able to use 1 packet of 8 to do all 10 fingernails because my nails are currently short enough that some nail strips could cover 2 fingers.
I would rate these better than Jamberry Nails but not as good as Sephora OPI strips. Unfortunately, Sephora seems to be discontinuing their strips but you can still find them on Sephora's website in their sale section and discount stores like Marshall's and TJ Maxx.
