Ties have no tag to prove they are made of silk. Every other real silk tie I've ever bought, whether it's a bow tie or a tie, has a tag that says it's 100% real silk. I believe they are actually polyester and they are advertised as silk. Assuming they are polyester I would say they are fine as long as you understand that they are not real silk.
