Our boards are made using Fuji Star paper (the premiere abrasives manufacturer in the world) which gives more longevity and overall better performance. We also use cerated dies which allows for a less problematic filing process and safer working environment. The cerated edge reduces the chance of cutting the client compared to the straight edged boards. The boomerang shape is great for working around the cuticle area, especially for those clients with sensitive/sore cuticles. Use for tailoring plastic tips and for shortening nail extensions or reducing thickness - hard gels and acrylics only. Fully sanitisable.
