Packing:




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.
 
+By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.
+By Sea: If the goods are will be shipped by sea, we will place a pallet on the bottom of cartons.
 
Shipping:
 
Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
a: The weight is under 40Kgs, we recommend to send them in shielding boxes to you by Express.
b: The weight is between 40Kgs-100Kgs, it can be sent by Express or Air.
c: The weight is over 100Kgs, we recommend to send them by Ocean.
