Several tips, all identical of course, so they are not for many sizes of screws; simply if one tip breaks, you can easily turn it to the other side, and once that one breaks too, you just throw it away and put in another. At 2.5 euros for 10, they essentially cost 25 cents each and have a tip on both sides, so that's 12.5 cents per tip.

For those who break tips on screwdrivers and drills, these will cover you for quite a while and they are also very cheap.

Once they all break, I will buy them again.
