Professional Nail Files A Quick 3-Minute Guide

Unlock the secrets of professional nail files in just 3 minutes! Learn about the selection and expert usage methods for these essential tools.

Each nail file has two different mesh numbers on both sides, which represent different thicknesses of sand grains. The larger the number, the finer the sand surface. On the contrary, the smaller the number, the rougher the sand surface. For example, 100/180 (100 means 180 will be rougher. The grit will be rougher. The size is also larger).

For new nail polishing strips, you need to use another polishing strip to smooth the edges of the new polishing strip to avoid damage to the finger skin during use.

Key Types of Professional Nail Files:

Thin Nail Files

Thickness: Approximately 0.15 inches

Materials: Wood, metal core, or EVA core

Grit: Typically 100/180

Purpose: Ideal for shaping natural nails, The rough surface can be used to trim the shape of the extended nail. The fine surface can be used to trim the shape of the own nail. At the same time, the rough surface can also be used to grind off the phototherapy glue that is not too thick, and can also be used quickly. Trim the length of the nails; the fine surface is used to trim the shape of the edges on both sides.

When using, try to polish in one direction and do not rub back and forth to avoid damaging the nails with excessive force.

Purpose: Suitable for removing gel polish,and replace the electric nail drill machine. The rough surface can be used to polish and shape acrylic nails. Because nails made from acrylic powder are harder, large-grain nail files are needed; the fine surface is can be used to carve and shape nails.

Choosing Professional Nail Files:

When purchasing nail files, consider potential issues that may arise during use. Based on customer feedback from online store, common problems include,

• The sand is rough and will damage the skin around the nails when polishing.
• The nail file is too soft and cannot be used normally.
• The grit on the nail file is not wear-resistant and will fall off quickly.
• Sandpaper separation, warping, and glue opening
• Too hard and inconvenient to use

To address these concerns:

Problem 1, the sand is rough

We polish the finished product again before leaving the factory to make it smoother on all sides. This step is very simple. It just adds one more piece of equipment and one step to the production. You can also polish it a second time before using it after you buy it back.

If your problem is that the sand grains are rough, resulting in poor polishing of the nail surface, then you may consider changing to sandpaper with a larger mesh count, that is, more fine sandpaper. Of course, the materials of sandpaper are also different. For detailed material issues, you can view our products Details.

Problem 2, too soft

This is due to the different quality of the EVA rubber core inside the nail file. Some EVA is thin, some is really thick, and the toughness is also different. However, due to different usage habits of each person, being too soft or too hard will become the cause of complaints. , if you are a wholesaler, you can tell your customers the difference in advance and let your end users choose according to their preferences.

Problem 3: The sand is not wear-resistant and will fall off

This is due to the different processes of sandpaper. Some sandpapers use sandblasting process, and the spraying is uneven and unstable, so it is easy to fall off. However, our sandpapers all use sand planting process, which is fine and washable, so the price will naturally be higher. Higher up, check out the video above to see the details and you’ll notice the difference.

Problem 4: Sandpaper separates, glue opens, and warps

Nail strips are made by pasting sandpaper and the inner core together. The quality of the glue, the pressure of the pasting machine, and the care taken during production will all cause this problem.
