Packing and Shipping Tips

1. Becuase the neodymium magnets have a very powerful magnetic force, strong magnetic force throughout.

2. Special package solution for this situation availble.

3. A customed iron box to hold the magnetic force inside, the outter box size is 35*25*15cm.

4. Thus makes air shipping possible, sloving the customers' emergency.Is there any grammatical error in this passage? Is it a literal translation from Chinese to English? If there are any errors, please correct the grammar without changing the original mea
