Why do you write obvious things? Even schoolchildren know this.
I do not sell diamonds or zirconium. I just pointed out your lies and attempts to deceive local users by selling supposedly useful things (the essence of which you cannot explain). But before that, you supposedly argue that you are developing something and suddenly selling “what you don’t need.” Do you think others are fools when you post photos of “pneumatic cylinders”?
Such individuals have already been here. Are you one of them?
