So, what is sealing wax? Well, back in the days of squires and knights, it was used to send letters safely without fear of tampering. It was also status symbol. Having a seal was reserved for royalty and prestigious professions such as lawyers or doctors.
Today, wax makes things like wedding invitations and branding look even more fancy and important but it can be used for any special correspondence. Plus, making wax seals is super satisfying and not that hard. If you're nervous, don't be. There's a crafty person in there, trust us.
