I purchased this at Yamada Denki about 3 years ago, and I'm selling it because I'm replacing it. It works without any problems. The original price was 25,300 yen. There is no instruction manual, but a PDF is available on the website. The following is from the product introduction site: Experience "light," "fast," and "shiny" with the touch of a button. This "shiny hair" dryer not only dries but also provides shine and scalp care. Product Features: The main body is lightweight and compact, weighing approximately 270g*, yet it's high-powered! The new "Tsuya Moist Dryer" quickly dries the roots of the hair and scalp, making it easy to use without straining your arms. It's easy to switch between the four modes: "Speed," "Scalp," "Tsuya (Shine)," and "Cool Down," which are gentle on the hair and scalp, with just the touch of a button. With the double care of negative ions and far-infrared rays, it suppresses dryness, frizz, and static electricity, leading to moist, manageable, and shiny hair. *Excluding the power cord ・Easy to operate with one hand and carry! Achieves industry-leading lightness. ・Powerful airflow for quick drying of hair roots and scalp! It delivers a powerful airflow that you wouldn't expect from such a small and light body. It dries wet hair, which is prone to damage, and the scalp, which can be prone to odors and itchiness, quickly and evenly. Negative ions and far-infrared rays prevent the hair from drying out too much, leaving it moist and smooth. ・Gentle "low-temperature design" that cares for hair and scalp while drying. The "Scalp Mode" is approximately 60°C and gentle on the scalp, and the "Tsuya Mode" is set to approximately 60°C or less, which automatically switches between warm and cool air. Both modes gently dry the hair and scalp, reducing heat damage while maintaining moisture. ・No complicated operations! Mode switching is easy with just one button. The four modes that are beneficial for hair and scalp are "Speed" (dries wet hair quickly), "Scalp" (dries hair and scalp gently at low temperatures), "Tsuya" (automatically switches between warm and cool air), and "Cool Down" (tightens cuticles and conditions hair). They can be operated easily with just one button. ・Airflow has 3 settings: Turbo/Dry/Set ・Negative ions x far-infrared rays suppress dryness and static electricity ・Maximum temperature: Approximately 90°C / Low temperature: Approximately 60°C
