Yes, we could produce customized size,shape magnets according to customers' requirements.Q4:Can I have a free sample before mass production?A: Yes. We could offer free samples if the magnets are in stock but you need to pay the delivery cost. It may take minimum 7 days for production if your size is out of stock.For neodymium magnets, we have many different size samples in stock.Q5:Can magnets could be shipped by air or by express ?A: We could ship the magnets by air or by express with our magnetic shield package.Q6. How about the quality of the magnets? A: To ensure the quality of the products, every production procedure is inspected strictly by the professional QC team from all aspect.Q7: Will the magnetism be weaker after use years?A: Yes, magnets do weaken over time.If you store permanent magnets correct, neodymium magnets will likely lose less than 1% of their flux density over 100 years.The magnetism decline is neglect, that's why we call it Permanent Magnet.
