My point exactly.

And to the above^

A finger weight is also known as a letter wait. You attach the bag to a hook and hold it up and see approximately (within .1-.5 grams depending on how you have it adjusted) how much the weight is. They cost 2 dollars maybe a little more if you buy froma smoke shop.

The most I've ever paid for one is 5 bucks and I rarely ever used it.
