Extremely impressed with the ultra speed fans, I used the 3D 0.7 on a client for a natural light volume set and they were so easy to work with! They came off the strip so easily without falling apart. The pointy bases made application look seamless and attach to the lash beautifully, (compared to others that I have tried that had very wide flat bases.) Highly recommend these promade fans to anyone that is after the best quality fans for their clients!
