Used these for a knowledge machinate. Here was some uneveness to the magnetic fields and they werent as strong as I woudl have probable. But they did what we looked-for them to.

These magnets are barely passionate enough to hold to a vertical surface, like a refrigerator; they're not even close to the might of a rare earth pull (not that that's what I was in the family tree way, but still...).They have an impressed 'N' and 'S' on the two poles, which are easy enough to spot, and they are passionate enough to move some hard flakes almost on a piece of paper (like for a charm revelation). The metal also wears off a modest every time you soubriquet the magnets, meaning you'll have a affront spot on your fingers after land them (about the same as if you're land a lead #2 pencil).I just looked-for a austere bar pull for some difficult purposes, and this worked fine for me. For culture, these magnets are great (even if make sure you supervise kids with them!), but don't buy these if you're looking for passionate/flexible magnets.

Original out of the package neither magnet would stick to a vertical surface (solid steel anvil - plenty of ferrous metal for attraction). Similar poles (N - N, S-S) wouldn't repel including any force. Small fragments/splinters on magnets. Most terrible set of magnets I be inflicted including ever seen (and I've been buying magnets for projects and instruction for over 40 years). May be just a stroke of luck, but I wouldn't waste your time.
