refridgerator magnets pin
Magnetic Pins made of 1 piece strong Neodymium disc (disk) magnet and 1 plastic mold. The magnet is mounted in a plastic shell with an ergonomically designed plastic handle for ease of use.
They are small, easy to grip yet very powerful.One magnetic pin will hold 35 pieces of A4 paper to a magnetic surface.
Color and size of magnetic pin can be made by customers’ requirement.

If you are convenient, we could talk face to face !!
We could let our customers in your country to help you send the samples, to let you check our quality faster!!
1.Products Magnetization
We can do all the magnetization for neodymium magnet including: Axial magnetization/Diametrical magnetization/Radial magnetization/Inner-diameter
multi-polar magnetization/Outer diameter multi-polar magnetization/Surface magnetization/Complex magnetization/Encoder magnetization/Skewed magnetization.
In order to offer better understanding of these methods of magnetization, please see below explaination.
2. Demagnetization Curves & Outgoing Inspection Report for each customer.
3. Standard Packing and Shipment
The package for neodymium we use: Sea Pallet / Air Carton / Express Packaging / Plastic Tube / Wooden Case / Vacumm Package and any other packing terms as per your requirement.
4. Shipping Details:
A: We have a discount price with Fedex and DHL. So if the weight is under 100Kg, you can those two shipping companies. But you can also choose TNT, UPS
or any other shipping companies if you like. We'll use iron boxes to shield the magnetics force for air shipping.
B: When the weight is over 100Kg,we think sea shipping is more reasonable. We have our own forwarder, you can also entrust your own forwarder.
C: Anyway, we'll respect your choices.
5. Payment
