・ Released September 2015 ・ Dretec Corporation ・ Model number DI-214 I have kept this item without using it since I received it, but I tested its operation before listing it for sale. I will use recycled materials for shipping. Also, since I don't have the original box, I will pack the item using bubble wrap, etc. The instruction manual will be folded for shipping. Returns and refunds are not accepted. Thank you for your understanding. I am also selling this item on another site, so it may be removed suddenly.
