For 18 you get to today handeslüblichen plastic weight plates blank filled with concrete
(Not as here asserted with sand). That there ever a few crumbs out crumbs can happen when you unpack, or even by any lubricant smell the rods has been applied to it like them to be protected against corrosion to be. I wipe them off with NEM dishcloth and all is well.
Also barbells and the thumb screws to secure are made of metal and not as claimed by some plastic here. In 30kg weight and a price of less than 20 this is certainly one of the most outstanding purchases worth at all!
The bars and the weights are not larger than all other dumbbell bars also,
some comments and recessions here I think is very borderline.
Especially when who is "not scientifically acceptable training" made the remark in his mouth and spoke in the same block of the bar will have to perform in biceps curls past the body.
Because I would rather times the author to advise the proper execution of Kurzhantelbizepscurls to let show :-)
