But really smaller than I wanted. Need to order again but bigger.

The 4x2 magnets are perfect for magnetizing 25 and 28mm bases (plenty of strength for things like chainrasps or pox walkers). 32mm through 50mm a single 6x2mm magnet should be fine. On larger models I used 2 6x2 magnets and they don’t move around in my transport case (black coach, space marine tanks, etc). These magnets are around N30 strength best I can tell.

These are OK, but advertised as 6mm x 2mm, and they are actually 6mm x 1.74mm. I have bought 6x2 magnets before, and those were actually 6mm x 1.94mm, and I thought I'd be getting the same thing. Different manufacturers apparently have different standards.

The magnet thickness is 1.7 mm and not 2.0 mm as advertised.

I used for the Intarsia magnet pieces I create. The odd size was challenging since I use forster bit to drill an indent into back to Insert Magnet. I use 1/4" and 3/8" normally. These were ever so slightly too small to fit. Some magnets I had to double up because they weren't as Strong as others I'd used in the past. overall, they did the job and the price was right.
