Glad to give you some suggestions on the Neodymimum block magnets
We are China industrial Block permanet Sintered NdFeB magnets manufacturer offer best industrial Block permanet Sintered NdFeB magnets OEM, ODM,service.

These block magnets are very common, we made them with round corner to protect magnets from damage or cause any hurt. Due to the strong attraction force, we used the plastic spacers among magnets .
