Lens Protectors 3MK Lens Protect HMD XR21 — set of 4 camera lens protectors

Set of 4 3MK Lens Protect HMD XR21 camera lens protectors designed to shield smartphone or device camera lenses from scratches, dust and minor impacts. Each protector is shaped to fit the XR21 lens module and offers clear optical transparency with a low-profile design to preserve image quality and autofocus performance. The pack contains four identical pieces for all camera openings in the module or for replacement over time. Material selection and precise cutouts maintain compatibility with flash and sensors while minimising reflections and colour cast.

Advantages

These lens protectors provide a near-invisible barrier that reduces the risk of physical damage without affecting photo clarity. The thin, tempered material resists scratches and everyday wear while retaining high light transmission. Adhesive is applied only around the edges to avoid interference with the lens surface and to enable bubble-free installation. A set of four gives full coverage for multi-lens modules or spare protectors for extended use.

Suitable for

• Smartphones or devices with the XR21 camera lens module
• Users who want to prevent scratches and dust accumulation on camera lenses
• Situations with frequent device handling where minor impacts may occur
• Owners who prefer low-profile protection that does not alter image quality

How to use

Clean the camera lens area thoroughly using the included wipe or a lint-free cloth and, if available, an alcohol cleaning pad. Remove dust particles with a soft dust removal sticker or use gentle air blowing. Peel the protective backing from the lens protector, align the protector precisely over the XR21 lens openings and press gently from the centre outward to secure it in place. If any bubbles remain, lift the protector slightly and reapply or smooth them toward the edge. Allow the adhesive to settle for a few minutes before using the camera for critical shots.

Usage recommendations

To maintain optimal image quality, avoid using strong solvents on the protector surface; clean with a soft microfiber cloth and mild cleaning solution if necessary. Replace a protector if it becomes heavily scratched, cracked or shows reduced transparency. Keep spare pieces from the set for future replacement.
