The Staleks Pro COMBO UNIQ 37 (WPPQ-37) is an elite professional replaceable attachment specifically engineered as a robust toenail file with a curved working end to deliver superior control and efficiency during advanced pedicure and podology treatments. This high-performance tip features a specialized anatomical curve on its working head, allowing podiatrists and nail technicians to easily slide beneath and around the corners of thick, tough toenail plates. The professional-grade abrasive surface is optimized to file away heavy sharp corners, painful spikes, and jagged edges that puncture the proximal and lateral nail folds. 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.
