Smooth Hardened Body Surface: The knob is formed from a high-density material that receives a multi-stage polishing process. The resulting glass-like finish resists absorbing household oils or moisture, and wipes clean without leaving a dull film Rounded Profile With No Sharp Corners: Every external edge of the knob follows a continuous curve. This geometry eliminates points or ridges that could press into fingers during pulling, and removes snag risks for passing clothing or cleaning cloths Pre-Drilled Screw Hole Alignment: The metal base has a single centered hole. Place the knob against the drawer or cabinet front, mark the screw position through this hole, then drill. The centered design self-centers the knob on the hole with no side-to-side adjustment needed Finger-Friendly Concave Pull Surface: The front face of the knob curves slightly inward. Hook your fingertip into this shallow dish and pull. The concave shape prevents your finger from slipping off during opening, even with a light grip Simple Wipe-And-Inspect Care: Clean the knob with a soft, slightly damp cloth, then dry immediately. Once per month, grasp the knob and attempt to rotate it clockwise and counterclockwise. If any movement is felt, remove the knob, apply a single drop of removable thread adhesive to the screw threads, and reinstall.
