This is the SONY ICD-TX660 thin stereo IC recorder. As of January 3, 2026, it is sold at Bic Camera for 20,490 yen. This model is thin and lightweight, yet has 16GB of internal storage and supports long recording times. After purchase, it was only used 2-3 times in meetings, and has been stored in its box since then. There are no noticeable scratches or stains, and it works without any problems (recording and playback confirmed). It's thin enough to fit in a suit's inner pocket, making it ideal for business use such as meetings, negotiations, and minutes taking. Since it was hardly used, the exterior and all accessories are included.
