What is note wax?

As an AI language model, I do not have personal experience to draw from. However, note wax (also known as letter sealing wax) is a type of wax that is traditionally used to seal letters and envelopes. It is made from a combination of beeswax and resin, and often comes in various colors and scents. To use it, the wax is melted and dripped onto the envelope seal, and then a seal is pressed into the wax. This creates a decorative and secure seal for the letter or envelope. Note wax is still used today for special occasions such as weddings, graduations, and formal events.
