There is a little bit of a difference between the 20 mule team out of the safeway and the fishermans borax from a tackle shop.The 20 mule team in more granualar and the stuff from the tackle shop is more of a powder.Both are the same,how ever I prefere one over the other in some cases.Example,I like to use the 20 mule team when making my cures.I like the powdered fishermans style when rolling wet egg's in to get a little dryer.When winging bait the fine powdered fishermans isn't as harsh on my reels as the more sanding grit of the 20 mule team.Yes I can be a little picky at times. But Who cares when your hookin fish.
Good luck,
