For the love of...here, once and for all.

An 8th (1/8) is a unit of measurement. 1/8 refers to 1/8 of 28grams (rounded down), so 3.5grams, no matter what you get, is a unit of measurement. 3.5grams IS 1/8 of 28grams

Understand now? Or shall I send you a gun.

It's cool that you get 4gram bags, but 4 grams is OVER an 1/8, half a gram over, so again, 3.5g's is a unit of measurement, it's not just a name given to the bags.

Good greif.
