Tempered glass screen protector 3MK HardGlass Max for Honor 400 — Black

The tempered glass screen protector 3MK HardGlass Max for Honor 400 in black is a precision-cut protective layer designed to fit the Honor 400 display. It provides a hard, tempered glass surface that helps guard the screen from scratches, everyday wear and minor impacts while maintaining original touch sensitivity and image clarity. The black edge finish aligns with the phone frame to create a discrete, integrated appearance.

Advantages

HardGlass Max uses a chemically strengthened glass layer that enhances scratch and impact resistance without adding noticeable thickness. The protector preserves touchscreen responsiveness and does not interfere with display brightness or color reproduction. The black border is matched to the device bezel for a neat visual fit, and the surface coating reduces fingerprints and facilitates cleaning.

Suitable for

• Daily protection against scratches from keys, coins and other abrasive objects
• Reducing damage from minor drops and knocks
• Maintaining screen clarity and touch sensitivity for regular smartphone use
• Users who prefer a protector with a black edge to match the phone frame

When it may not be suitable

This tempered glass protector is intended for everyday protection and may not prevent damage from very high-impact drops or severe bending forces. It also may not fully cover devices with non-standard curved edges or aftermarket display modifications.

Key specifications

• Material: Chemically strengthened tempered glass
• Finish: Black edge to match device frame
• Surface treatment: Oleophobic coating to reduce fingerprints
• Thickness: Low-profile tempered glass designed to preserve touch sensitivity
• Compatibility: Cut and shaped for Honor 400 display dimensions

How to use

Clean the phone display thoroughly with the included cloth and dust-removal sticker, position the protector over the screen aligning the cutouts and edges, and apply from one side while smoothing out air bubbles toward the opposite edge. If small bubbles remain, press them gently toward the edge with a soft card or cloth. Follow any included installation guide for best alignment and adhesion.

What to consider before purchase

• Ensure the protector lists explicit compatibility with Honor 400 to guarantee proper fit
• Check whether a case you use may lift the protector at the edges—select a case-compatible protector if needed
• Verify included accessories (cleaning cloth, dust sticker, alignment tools) if precise installation is important

Usage recommendations

For optimal protection, replace the tempered glass if it becomes cracked or seriously chipped; even small cracks can reduce protective performance. Clean the surface periodically with a soft, lint-free cloth and avoid abrasive cleaners to maintain the oleophobic coating and display clarity.
