Don't miss your favorite programs, news, or sports! [Can be Stood Up with Coins] You can stand it up by using the included stand parts or inserting your own coins into the stand slits on the back of the main unit. Thank you for viewing. I purchased this on Amazon for Mother's Day this year (about 9000 yen) and gave it to my mother at her parents' house, but unfortunately, One-Seg did not work because it is in the countryside, so I am listing it. Just in case, I had my family who live in the 23 wards of Tokyo check the operation, and it worked without any problems (photo 8 is from that time). How about it for those who live in the city? Although it is new and unused, please understand that it may not work depending on the radio waves in your area, and please refrain from returns or claims. When shipping, I will fold the box, wrap the product in bubble wrap, and deliver it by Nekopos.
