What can I use in place of Fudge Dice? [closed]

If someone doesn’t have any fudge dice, what are the best methods to replace them and why?

Term: Fudge Dice are six sided dice with two sides labeled with a +, two sides with a -, and two sides that are blank. They are usually rolled in groups of four, and the + and – sides are added together to get a number between -4 and +4, with positive usually being better.
