Disposable files-sponges for short nail file EXPERT 51 Staleks, grit 120, x 20

EXPERT 51 disposable files-sponges 120 grit, the softness of foam at the service of filing

The STALEKS EXPERT 51 disposable files-sponges are self-adhesive abrasives of a particular kind: instead of sitting on a simple paper backing, they rest on a flexible foam support. Part of the EXPERT 51 family, they keep the short format of that range and fit the same short bases as the other EXPERT 51 consumables. Supplied in a pack of 20 pieces, they are offered in 120 grit, an intermediate abrasiveness ideal for working the material without being harsh on the nail plate. Like every Staleks disposable file, they are stuck on for the length of a service, then peeled off and discarded, while the base is cleaned, disinfected and sterilised between two clients.

The foam backing, the argument that changes the movement

This is the real difference of this reference. A rigid abrasive stays flat, whereas the nail is curved. The foam support of the file-sponge compresses slightly under pressure and follows the natural curve of the plate, putting more abrasive surface into useful contact.

The benefit is immediate: the pressure is spread instead of being concentrated on one edge, filing becomes gentler and more enveloping, and the technician applies less force for an equivalent result. This is particularly welcome on thin nails, on the sidewalls and whenever a material transition needs softening without digging in.

The comfort is felt on the client's side too: the sensation is less dry and less vibrating than with a rigid abrasive, which makes the service more pleasant, especially on sensitive hands.

120 grit, a very useful in-between

To place 120 grit correctly, it helps to look at the abrasive scale used in nail care:

• 100 grit: the sharpest, dedicated to working gel and acrylic and to roughing out builds.
• 120 grit: slightly finer, it still works the material efficiently while offering a more progressive pass, which limits the deep marks you would otherwise have to correct.
• 150 grit: the abrasiveness of shaping artificial nails.
• 180 grit: the grit of the natural nail and of shape finishing.
• 240 grit: the gentlest, reserved for finishing, the free edge and thin nails.

Combined with the flexibility of the foam, 120 grit is therefore at ease when adjusting a length, refining the thickness of a set, preparing a repair or evening out a surface before finishing, with a firm yet controlled action.

Designed for the EXPERT 51 short file

These refills belong to the EXPERT 51 range and keep its short format: they fit the same short bases as the other disposable files in this family. As the official product sheet does not name a base reference, it is wise to check the packaging or the compatibility of your holder before ordering. The short format is handled with the fingertips, like a precision tool: it makes it easier to work small nails, corners and targeted touch-ups, and it slips easily into a mobile kit.

The metal base brings rigidity and hold, the foam brings flexibility: the combination of the two gives a tool that is precise in the direction of the movement and forgiving on contact with the nail. It is this balance that has made files-sponges so popular with nail technicians.

A new abrasive for every client

The Staleks system relies on a simple rule: the base stays, the abrasive changes. The disposable file-sponge is a single-use consumable: it cannot be washed, disinfected or stuck back on once removed. After the service it is discarded with the session waste, while the base goes through cleaning, disinfection and sterilisation according to the salon protocol.

This routine eliminates any transfer of nail dust or gel residue between two clients. It is visible, easy to explain at the workstation, and immediately reassuring for clients who pay attention to hygiene.

Applying and removing the sticker in seconds

1. Check that the base is clean, dry and disinfected before application.
2. Peel off the protective backing on the reverse of the file-sponge.
3. Carefully line the abrasive up with the base and press from one end to the other, without crushing the foam, to expel the air.
4. Carry out the service and let the abrasive work: the foam takes over part of the pressure, so there is no need to press hard.
5. Dust the abrasive regularly with a brush to keep its bite.
6. At the end of the appointment, lift the file by one corner, discard it, then clean, disinfect and sterilise the base.
