Description: I took apart a weighted belt and discovered the weights are made of plastic bags full of iron filings. The quality is not that good, so I also bought some on eBay that was much better. It was a fun day in the shop! Here is the eBay link I used, the quality is great! ebay.com/itm/132988338020
