3 Swords Germany - brand quality 12 piece manicure pedicure kit set - nail care tools - Made in Solingen Germany (258)

Are these authentic sets?

Is this product authentic? it doesn't say anywhere "made in solingen germany" just germany or solingen, which means nothing.

In the item description I read "Material steel implement â€" nickel plated shiny". 1) What does it mean? 2) Is it stainless steel? Thanks in advance,
