The secret tsukira is a paper that can be inserted into the edge of the paper folded into the unit to hide the message. Use it as a communication tool at school or in the office, or as a gift to give as a message card. Write a message on the front and fold it back and insert it into the slit to reveal a wrist of beans. Featuring an adorable bunge's design that you will want to open, it makes a great easy and fun communication tool for renting objects or giving a gift. 20 sheets (10 sheets x 2).
