Iron Filings in Plastic Case
Used in education for field mapping, these can be used with magnet toys and for many other applications. Filings so light and smooth that they can be picked up by any magnet and then restored in the secure plastic case. The case is not to be opened and closed, but rather the filings can be manipulated within the case. The weight of the plastic case with filings is approximately 3.3 grams.
Ages 7 and up.
Keep magnets away from Computers and Gadgets.
