While the size seem to be correct(Diameter of about 18mm and thickness of about 1mm. By the way, I use a normal ruler) and it don't stick to a magnet, what bother me most is that its reed on the edge are very .....poor.(as seem in the picture)
Please, I have no idea if it just in a less perfect condition or it was a counterfeit and I surely need some help
Thank you.(and sorry for my poor english)
