Can envelopes with wax seals be mailed through the Post Office?
Modern Sealing Waxes are mailable and flexible - people have mailed sealed envelopes through the modern postal service for dozens of years. Using modern flexible and mailable sealing wax applied directly to the envelope is the best way to ensure that your wax seal will stay intact through the process, even with modern postal sorting machines. Damaged seals can happen but are a rarity. Hand cancelling by the Post Office can add an additional layer of security. Pre-made Adhesive Wax Seals are also mailable and flexible - we use a high bond adhesive double-sided backing that stands up very well to modern mailing and sorting machines. While we cannot guarantee 100% that there will never be a "snag" in the mailing, we know from our users and from test experiences that this is indeed a rarity. Again, hand cancelling by the Post Office can add an additional layer of security.
Traditional Sealing Waxes are not mailable and should be used for decorative purposes only. When it comes to traditional sealing wax, these are less flexible and should be mailed in a protective envelope and/or hand cancelled. Original Formula Bank Wax is completely breakable and is used more for decorative purposes and therefore is not recommended for mailing on an outer envelope. Mailing Sizes: The largest recommended size that is mailable on the outside of an envelope is the 1 1/8" die (finished wax seal 1 1/4"). Any larger wax seals are over the regulations set by the Post Office and are more likely to be damaged by the postal sorting machines or rejected by the Post Office.
