We've discounted the price by 8,000 yen for an end-of-year sale, valid until 12/20. The price will return to its original amount after the New Year! Purchased in June 2025 and used a few times. The D-4T malfunctioned in August and was replaced. It has been used a few times since the replacement, and there are no problems. I will need some time to ship due to work, but I will ship within the set deadline. Thank you.
