Shipping Errors or Damaged Product
Shipping cost for returns will be the responsibility of the customer unless the parts are incorrect or damaged upon arrival. For shipping errors or damage, SuperMagnetMan will bear the cost to replace the parts and the return shipment for the incorrect or damaged product. Custom orders cannot be returned unless the parts are incorrect or damaged. For details on returning parts, contact our shipping department at 205-621-8841 or email firstname.lastname@example.org for instructions.
Parts returned at the discretion of the customer will be subject to a 10% restocking fee. This policy applies only to orders received from our online store.
If possible, please ensure that all products are in their original packaging to avoid damage during the return shipment. The customer will be responsible for shielding the magnets properly so that the box or envelope is not magnetic at the surface. If a paper clip sticks to any side of the package more packing material (sheet metal, foam wrapping, peanuts, etc.) or a larger box will be required. If the parts are not properly protected, there is no guarantee the return will make it back to us in its original condition, and a refund will not be issued.
If replacement parts are not needed, refunds will be issued for parts only once they are returned returned to our facility in the same condition they were shipped. This does not apply if the return is for incorrect or damaged parts.
It is important to us that you are happy with your order. Please contact us with any questions or concerns.
Thank you for your business!

I needed a tube magnet with an ID of a maximum of 1mm. I could not find it anywhere else except here. In my research, I needed to stimulate a flow through a pipe by a strong magnetic field. So, I needed a tube magnet with an ID close to the OD of my tube as much as possible. However, it would have been perfect if I was received the map of the magnetic field in the axial and diametrical axis. Now, I have to prepare such a map by sophisticated software like COMSOL. By the way, when I started the experiment by these magnets, I was worried about the accuracy of dimensions. I measured that, and it is accurate enough! Also, I align the diametrical tube magnet along the axial axis and they are stable ( I mean they could have repel eachother because they designed to attract each other when they become arranged next to each other not on each other), which means the magnetization of N and S pole are perfectly accurate.
