I hereby agree to the statements on the seam. I find that I have perceived the seam in my set only based on the reviews right here. Tried to photograph the seam. In the right empty mill the seam is easy to see on the left the middle of the glass in the picture. If the mill filled with pepper, the seam is imperceptible to me, if you do not look for it directly. The other quality of the mill's undisputed good to very good. I hope I could convey the theme with the seam something. Was this review helpful to you, I would appreciate a yes at below tuning capability.
