Looper / product


If you want to exchange a book with other readers, you take a registered electronic ticket and have it scanned by the sensor. Then you will receive a strip of paper used for sealing from the machine. Leave a message on the strip, wrap the book using the strip, and throw it into the machine.
After turning the rotary switch, you will obtain a book selected by the machine randomly.
