China
Seriously, i didnt say china just to be funny. There are alot of chinese manufacturers online that make fishing jigs but you need to buy BULK, like 1000 jigs or something. I emailed a few couple of years back regarding tungsten jigs, which look just like the ones sold on yoursbobberdown and the price they gave me was fairly low per jig but i dont need 1000, especially 1000 in one color/size/form. I am pretty sure all these sites that claim their tungsten jigs are made in sweden, finland are actually manufactured in china but packaged in finland, sweden, etc.
