Product Features
This 70x10x3mm block neodymium magnet features strong 3M adhesive on one side for easy and secure attachment to non-metallic surfaces. The adhesive is durable and reliable, providing a strong hold while maintaining the full magnetism on the other side.
The magnet itself is made of high-quality neodymium iron boron material. Its long dimensions, despite its thinness, provide a strong and stable magnetic force. A smooth epoxy coating effectively prevents corrosion, peeling, and abrasion, ensuring durability and a pristine appearance.
This precisely designed black rectangular adhesive magnet boasts strict dimensional and magnetic tolerance control, combining reliable attraction, strong magnetic pull, and a robust, durable construction. The 3M adhesive backing enhances its versatility, allowing for quick and easy installation without compromising performance.
User Guide

How to separate a magnet
1. Carefully slide the top magnet out of the pile of magnets.
2. Gently lift the magnet out of the pile.
3. Continue lifting until the magnet is completely separated.
Note:
1. Do not pull, lift, or pry the magnets from the pile before sliding them to one side.
2. The white pad can be kept and reused.
3. Avoid collisions between magnets or sudden adhesion to any magnetic surface, as this may damage the magnets.

Two ways to use
1. Metallic Surfaces: The magnets can be directly attached to any metallic surface without the need for additional adhesive.
2. Non-metallic Surfaces: Use the 3M adhesive on the back to firmly attach the magnets to non-metallic surfaces, ensuring reliable adhesion and maintaining their magnetic properties.

Applications
These adhesive backed block magnets are versatile and suitable for various everyday uses:
Tool Room: Securely holds small tools, screws, or metal parts, keeping your workspace neat, organized, and easily accessible.
Refrigerator: Attach sticky notes, photos, or lightweight items to the refrigerator without damaging its surface.
Kitchen: Neatly hold tableware, spice jars, or kitchen accessories to magnetic or adhesive surfaces.
Storage and Organization: Ideal for storing office supplies, craft materials, or small electronics on both metal and non-metal surfaces, providing a convenient and tidy solution.
