These are well made product that will be perfect for my project.

I am Irish so I probably have a better eye for the authentic symbols but not being a purist, if it looks good to you it is fine. The plastic quality is good, the little hole for keeping them together on the little supplied chain can be taped of course.I'm only dropping a star as the research by whoever made them is not great but most are nice, only three or four I wonder why they bothered with these.
