The Staleks Pro COMBO UNIQ 38 (WPPQ-38) is an elite professional replaceable attachment specifically engineered as a straight toenail file to deliver superior control and efficiency during advanced pedicure and podology treatments. This high-performance tip features a straight, robust linear file profile that allows podiatrists and nail technicians to smoothly access the lateral folds and perfectly flatten and square off the side walls of thick, tough toenail plates. The professional-grade abrasive surface is optimized to file away heavy sharp edges, jagged corners, and pressure points that can lead to painful ingrown toenails and tissue inflammation. Forged from high-alloy medical AISI 420 stainless steel, the tip includes high-precision external threads that anchor securely into any UNIQ series modular handle, ensuring a completely rigid, vibration-free single-tool feel and ultimate durability under continuous professional sterilization.
