More and more people are reluctant to use the traditional wax-sealing method when they seal letters due to its
complex operations. With the help of modern technology and delicate design, one-off spray foam and copper seal
are applied into sealing letters. By this means, operations are simplified and the traditional practice of sealing
letters is well presented.
