1. Cover the nails and edges with nutritious oil first. If you want to omit this step, you can just soak your hands in warm water for a while.

2. Push back the dead skin at the bottom with a push rod. Don't push it too deep, it will grow quickly and be easy to clean.

3. Clean the pushed dead skin with a cotton swab.

4. Take out the fine grinding rod and rub it vertically and horizontally on the nail surface, paying special attention to the part where the dead skin has just been ground.

5. Then use rough grinding to help polish your nails, and don't miss any side edges. Long nails can be trimmed with nail clippers before they are taken care of.

6. Finally, apply some nutritional oil on the polished rod and polish the nails, but this will hurt the tools, so you can also polish the nails with the polished rod first, then apply the nutritional oil on the nails and massage them a little.
