Ignore all of these people. They just don't know good quality Kratom when they see it or haven't bought from KUK for a while. You see, although KUK are known for their gritty texture, it's not JUST sand. It's M&S sand. Usually 9 parts Kratom, 1 part M&S sand. Me, being the connoisseur I am, I also now add sand to ALL my Kratom powders. Unfortunately I'm too poor for M&S sand but find kids play sand next best.
