Strong Rare Earth Permanent Small Disc Magnet NdFeB Button
Neodymium Iron Boron (NdFeB) Magnets
Neodymium Iron Boron magnets are a type of rare earth alloy that typically has two atoms of Neodymium (Nd), 14 atoms of Iron (Fe), and one atom of Boron (B) as its primary elements, hence their chemical composition Nd2Fe14B, which is commonly abbreviated as NdFeB. There are other elements that are used to increase the coercivity, to gain lower oxidation characteristics, and to obtain other desirable characteristics. These elements are used to "dope" the alloy and are generally found in small quantities (<10% by weight).
Sintered Neodymium Iron Boron Magnets
The sintered Neodymium Iron Boron magnet is produced by the OPS (orient-press-sinter) method. A crystalline alloy of Neodymium, Iron, and Boron is ground to a sub-micron powder using a ball mill, then aligned in a strong magnetic field, and pressed into a basic shape. The resultant "block" is then sintered, thereby fusing the material into a solid metal.

Packing
1. By Sea: As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton. (Detailed package quantity should be made upon the real products)
2. By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.
Shipping: Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
