150pcs 3x3mm Refrigerators Magnets DIY Multi-Use for Fridge Door Whiteboard Map Bulletin Boards (3x3mm)

Good all around size for large Warhammer minis

Dimensions were accurate, and they are magnets.

Great product, just what I needed....highly recommended product!

As described

These are really strong. Dimensions are a bit off; I measured them as 2.84-2.90 mm diameter and 2.85-2.90mm thick. I'd take a point off for that, but it means that if you design the hole as 3mm and 3D print it, these fit nice and snug with that 0.1-0.2mm loss you get when 3D printing a hole. Also, they are just so strong for the size that I can't give them anything but a 5 star review.

as expected
