NPI provides Jemits Tape, specialty film for confidential/private letters. This was developed with Kyokuetsu Corporation, Inc. and is the first implementation for the purpose in Japan.

A postcard made from Jemits Tape can contain three times the information that a normal postcard can, and its glossy finish extremely popular.

It can be used for direct mailings, tax certificate slips, lotto, ballot papers, notification mails, cards and many other applications.
