not nearly enough, but it's good for about 3 sample bowls each in a good size pipe. I just got them friday and only tried longbottom leaf which was very mild and pleasant with an awesome aftertaste, then shortcut to mushrooms which was really unique and enjoyable. quantitatively i would say only about 3/4 oz each. it's not a bad deal at all especially if you want to try the blends before buying in bulk.
i immediately bought 2oz of longbottom leaf. probably should have waited till i tried them all so i could just buy a sh!tload of each.
