A great grinder. It is eay to fill. I put whole peppercorns inside. The shaft goes all the way through so you can adjust the coarseness or fineness of the grind . It is clear so you always know how much is inside. It is a nice looking grinder too. The lid you remove to fill is also what you turn to grind once put back together and gives you an easy to grip turn. #Rankboosterreview #Sponsored #CUSIBOX https://www.amazon.com/Grinder-CUSIBOX-Stainless-Adjustable-Coarseness/dp/B075YRMQV3
