6mm x 3mm Round Neodymium Magnets (Nickel Plated or Black Epoxy

Super strong, these tend to slide across the table to find a matching magnet if you're not careful about keeping them sufficiently apart. The price is great too!

It's a nice, strong magnet. Actually 6x3

These magnets are MUCH stronger than I expected. I had purchased what I thought were "super strong" magnets from Amazon. If you need true N52 magnets this is the place to purchase them. Fast shipping also. I now have a need for another size, I hope West3D has them. Won't waste my time buying somewhere else.
