Cool to play with- Get the magnets with this.
I bought this for my sons for Christmas with the super strong magnets that are recommended. I put these in a big glass jar and it's just cool to see how the magnets work with this. A note of caution- my son put the magnets directly in the powder and we're having a hard time getting these to come off the magnet. These are really cool to see play with

Iron shavings
Bought to use in resin projects. Have small tic, tac, toe set. Added this to the "X's and O's" and small magnets to to the board. Works great. Looking forward to using this in in resin with magnets to create designs.

Entertaining and educational
My son enjoyed this for two enchanting long sessions. For that it is well worth it. On the down side, I live in one of the driest climates on the planet and this powder still rusted. Also, it stuck all over our magnet collection. I had to buy one powerful magnet to clean the iron off all our other magnets. If you are like me and see value in this for your kids, you may also want to get them some sand to pull the iron out of it with a magnet. Fun.

Magnet fun!
It's fun to change the magnet orientation & see the field lines change. We need to be careful with the magnet (to not break the glass). I live in the desert, so rust isn't really a concern for me over time.

The filings themselves are fine but I ordered 2 and one of the was open and completely empty when it arrived. I was quite annoyed since they're aren't very cheap.
