Internal mailing envelopes

Internal mail envelopes are equipped with a two-sided surface division and viewing holes as standard. This makes these envelopes ideal for sending internal mail. The envelopes are designed to be used multiple times, and thanks to the sturdy kraft paper they retain an attractive appearance.

It is possible to produce your own envelope. The material, size and printing can be completely customized to your own wishes.

It is also possible to customize the envelope closure. You can choose from a Velcro closure, an unrummed closure, a multilock closure or a rope closure (Japanese clasp).
