22 pounds of high quality, natural magnetite powder. Images show an 11 lb bag (you will receive 2 of these), a small example of the material, and a compositional analysis. Great for hydroponics, gardening, MEOW kettles and experiments of all kinds. Lowest delivered price per pound.

1 cup of magnetite powder weighs about 1 lb.  The material feels and handles like (very heavy!) bread flour.  It is sifted and dried.

Regrettably, once again I have had to increase the total cost due to USPS shipping rate increases.  Any price increases in the last five years have been due to USPS shipping cost increases, which is out of my control.  If there was a cheaper way to ship, I would use it.  However my product price has remained the same for the last five years - no inflation!
