Screen protector film 3MK Lens Protection for Realme C21 — 1 pc

3MK Lens Protection for Realme C21 is a single-piece protective film designed to cover and protect the device’s camera lens area or small screen surfaces from everyday damage. The film is thin and clear to preserve optical quality while reducing the risk of scratches, dust build-up and minor abrasions that can affect photo clarity and device appearance. The pack contains one protective film made to fit the camera module or specified flat area of Realme C21.

Advantages

The protective film is optically transparent to maintain image sharpness and color fidelity while providing a low-profile barrier against mechanical wear. Its adhesion is formulated to stay in place without leaving significant residue when removed. The thin design keeps the original fit and aesthetics of the device, and the material resists minor smudges and fingerprints to help maintain clear shots and a neat look.

Suitable for

• Protecting the camera lens area of Realme C21 from scratches and dust
• Replacing aged or damaged lens film to restore protection
• Everyday use to reduce wear from pockets, bags and handling
• Users who prefer a thin, unobtrusive protective layer for optics

Key specifications

• Compatibility: Realme C21 camera lens area / compatible flat surface
• Quantity: 1 protective film
• Material: thin transparent protective film designed for optical clarity
• Finish: clear, low-profile
• Primary protection: scratch, dust and minor abrasion resistance

How to use

Before application, clean the lens area thoroughly with a lint-free cloth and, if available, an alcohol wipe to remove oils and dust. Carefully align the film with the camera module or target surface on the Realme C21, then apply from one edge, smoothing out air bubbles toward the opposite edge using a soft card or cloth. If small bubbles remain, they typically dissipate within 24–48 hours; if necessary, lift and reapply carefully to correct alignment.

Usage recommendations

Store the film in a clean, dry place prior to application. For best optical results, avoid using abrasive cleaners on the film and replace it if deep scratches or persistent clouding appear. When removing, peel slowly at an angle to minimise residue; if any adhesive remains, remove it gently with a suitable adhesive remover safe for phone finishes.
