FAQ
Q1. Why is the price of sample higher than that of batch?
A: For samples we don't have any profit. We only charge the cost of materials and labor. As a manufacturer, the more quantity produced, the lower the unit cost.
Q2.Why do I get magnets that break so easily?
A: Magnets are designed to be brittle and fragile. Remove the metal from the working area before using the magnet. Keep the distance between the magnets when using them at the same time. Even small magnets attracted to each other can break with such force.
Q3. Do you support exchange and return service?If I buy a magnet and I can't use it.
A: We do not support return or exchange service. As you know, the magnet is a custom product, which is completely customized according to your requirements. This product cannot be resold to others.
Q4. What will you do if there is a quality problem?
A: If you have any problem after receiving the magnet, please contact us immediately and shoot a video to us. We make records and take pictures of all the details when we ship. If it's our fault, we'll take the blame. If it happened in transit, we are not responsible for it.
