• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 0.7 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating
• Magnetization: Axially magnetized (Poles on the large flat faces)
• Shape: Ultra-Low-Profile Stealth Wafer

Material Description:

Our 8mm x 0.5mm N52 discs are engineered specifically for applications where vertical space is tightly constrained. The 8mm diameter provides a broad, stable footprint that distributes adhesive contact evenly, preventing the magnet from shifting or peeling under shear force. At just 0.5mm thick, these micro-wafers can be hidden directly between layers of heavy paperboard, laminated within premium packaging, or placed under thin fabrics without causing any noticeable rise or texture change.

Handling Advice: CRITICAL NOTICE: These magnets are exceptionally fragile and delicate. Due to their extreme thinness, they have zero flex and will crack or shatter like micro-thin glass if handled roughly or allowed to snap together violently. Always slide them apart horizontally with extreme care. We highly recommend using plastic or non-magnetic tools during assembly.

Warnings and Safety Information:

• Fragility Hazard: Highly brittle. Will shatter instantly if snapped together. Handle with delicate care.
• CHOKING HAZARD: Micro-film size is a severe danger to children and pets. Keep strictly secured.
• Ingestion Warning: Swallowed magnets can attract through internal tissue, causing fatal complications. SEEK IMMEDIATE MEDICAL ATTENTION if swallowed.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants.

Applications:

• "Stealth" magnetic closures for premium wedding invitations, high-end greeting cards, and mailers
• Invisible closures for ultra-thin luxury gift boxes, cosmetic cases, and jewelry packaging
• Low-profile magnetic attachments for delicate electronic components and wearable tech sensors
• Concealed fastening systems for lightweight fabric linings, small wallets, and leathercraft
• Precision magnetic alignment tabs for low-clearance 3D-printed assemblies and model crafts
