Laser Pointer ELECOM ELP-RL07PBK Contents: → Main unit / 2 AAA batteries / USB receiver (can be stored in the main unit) Box (included as a back-side instruction manual) Purchased at Yamada Denki and used a few times for presentations, then stored. The main unit is in good condition both in appearance and function. Highlights explanations with a red laser. It's very convenient as you can advance and go back pages in PowerPoint by pressing the forward and back buttons. I will include the 2 AAA batteries I bought for the operation check. I will include the box as a back-side instruction manual, but please note that I will fold it to fit. The main unit will be securely protected for shipping. Both the red laser and the forward/back functions have been tested and are working without any problems. Thank you for looking.
