Material Description:

Our 3x0.5mm N52 discs are engineered for "invisible" applications. Because they are nearly as thin as a business card, they are the preferred choice for premium stationery, high-end packaging, and delicate micro-modeling where a standard magnet would be too bulky.

Handling Note: These magnets are extremely fragile due to their thinness. Do not attempt to pull them apart; always slide them carefully. They can crack easily if snapped together or handled with metal tools.

Warnings and Safety Information:

• Choking Hazard: Micro-size is dangerous for children and pets. Store in a secure, labeled container.
• Handling: Use extreme caution. These can be difficult to pick up due to their flat profile; use plastic tweezers or a sliding motion.
• Medical: Keep away from pacemakers and other sensitive electronic implants.
• Electronics: Safe for most modern devices at a distance, but avoid direct contact with magnetic storage media.

Applications:

• High-end wedding invitations and "Save the Date" cards
• Magnetic closures for luxury cosmetic packaging
• Micro-miniature detailing (e.g., swappable components on 15mm scale figures)
• Precision sensors in ultra-slim electronic devices
• Hidden magnetic latches for lightweight balsa wood models
