Pure black ball type neodymium magnet

Black coating specification.
Unlike round type and square type, I often customized a black coated neodymium magnet (N35), because it is often used in visible places on the surface.

The black coating is relatively solid, and the color does not balance in the collision of the magnets etc, but please be careful as the paint will peel off if you sharp objects such as a cutter or if you hardly scratch hard objects.
Also please do not immerse in thinner for model etc for a long time.
It is necessary to keep the surface in contact with the magnet as smooth as possible.
Round heads of insect pins and round neodymium magnets are suitable for receiving magnets.

Supplement
The solidity of the coating is greatly different from the 4 mm diameter spherical magnet that we sell earlier.
Prior sale products were coated with black epoxy resin, but in model applications it is not necessary to have surface strength as much as epoxy resin, so downgrade according to the model application.
It is the release item of this time that changed the coating method.
The coating of epoxy resin is certainly solid and coating does not fall even with thinner, but it was costly and we were struggling to sell.

The new one dissolves in the tool cleaner for model when it is dipped for a few minutes.
Painting is not a prerequisite.
Please use the black coating as it is.

We have enlarged the size to 3 ~ 6 mm in diameter, supposed to make a magnet joint own work.
Please use the black coating in addition to the joints and discover new ways to use it.
