Tired of spending hours filing square nails that damage the natural nail?
Thick, bulky results. Excessive filing. Two-hour appointments. The problem is not your product or your hands—the problem is that nobody has taught you the exact flash curing sequence, dual form selection method, and flush cuticle placement that reduce the need for excessive filing.

This course teaches a no-file approach designed to reduce filing and improve efficiency, helping you create professional square nail shapes with flush cuticle areas whilst protecting natural nail health.

Student Testimonials
“I struggled with square nails for years. Within two weeks of learning the no-file dual form method, I was creating perfect Instagram squares on every client. My appointment time dropped from 2 hours to just 70 minutes, and clients cannot believe how comfortable the application is.”
— Zoe., Artistic Touch Student ★★★★★
“I wasted three months watching YouTube videos and ruining practice nails before I invested in proper training. Within one day of Radina’s course, everything clicked. I finally understood why my attempts were failing and how to fix them. Best investment I have made in my nail career.”
— Emma L., Certified Nail Technician ★★★★★
“I wasted two months and over £200 on products that did not work before I invested in Radina’s training. The course paid for itself after just three clients because I finally understood which products to use and how to apply them properly. I wish I had started here instead of wasting time on free videos.”
