Pierre Cardin Vintage Filigree Pen and Pencil Set- 521 $50 or $45 w/offer

This Pierre Cardin vintage filigree pen and pencil set I bought back in the 1990s but never used it. I just thought it was beautiful. I do not see myself using them so selling them. These are rare set as it was, when I did buy them back then these were the only set of this particular style the store had. I believe the metal is stainless steel. The set has a lifetime warranty but as I no longer have the receipt, so I am not sure how that works.
