BOXXX Is a texting reference to 100 1lb packages of weed x 10 or 1000 lbs Sometimes also referred to as a case. Associating 1000 lbs of weed and the word case is a bad omen to some and preferably not used. So expanding the quantity value a box x 10 (x) conveys 1000 lbs. Its another way to say 1000 lbs of weed.
There are multiple strains and more then a boxxx available.
