Why We Teach E-File

E-file techniques are essential for modern nail professionals. At TWENTY, we believe in working smarter, not harder.
The E-file allows for:

• More efficient and thorough nail prep

• Smoother product application

• Reduced strain on your hands and wrists

• Quicker, safer removals

• Better retention through precise refinement

Learning how to use the E-file properly means you can cut down on appointment times, increase bookings, and ultimately boost your income—without sacrificing quality.

Your Qualification

This is an accredited course, and upon completion you’ll be required to submit two case studies demonstrating your understanding and execution of BUILD & BOOST builder gel services. Once approved by your educator, you’ll receive your official Builder Gel Certificate, allowing you to offer these services professionally and confidently.
