Your smile and a firm handshake will tell them you can be trusted, but having these Trust Me cufflinks for Real Estate Agents sure wouldn’t hurt! But please don’t think we are biased. We carry these for Doctors, Lawyers, and Accountants!
These seem like a promotional item marketed, of course, to real estate agents. It's a little bit cheesy, I think, but would be perfect for someone who was very enthusiastic about their job as an agent.
