【Developed and Supervised by Tadashi Kaneko】Latest Model S Tasuki Light eX Black L-LL Purchased in November 2025, only tried on once over clothing. I am selling it because the size didn't fit. The outer box has some tears. About this product: Supervised by stretch trainer Tadashi Kaneko! The "S Tasuki Light" was developed, focusing on the traditional Japanese beauty posture item "Tasuki-gake" to reduce the burden on the neck. It supports the continuation of beautiful posture by applying the ideal pressure of Kaneko stretch. The gentle tightening helps you maintain the points of beautiful posture even when you're not wearing it. The important thing is to put the first thoracic vertebra in the correct position. It approaches 4 joints and 5 bones! Corrective support for 25 muscles simultaneously. Unisex. Description: "Adjust beauty and health from posture" -- "S Tasuki Light eX" was born under the supervision of Tadashi Kaneko, a leading expert in posture and stretching. With the latest compression design and stretch structure, it guides you to the correct posture while firmly supporting the upper arms. The unique "S Tasuki" structure naturally aligns the balance of the shoulders, arms, and back, making it comfortable even for long hours of desk work or standing work. It is a compression arm innerwear that is ideal for daily life, training, and body making, regardless of gender. The high-stretch nylon and polyurethane compression material tightens the sagging upper arms and keeps the posture line beautiful. It is easy to wash and does not lose its shape, making it easy to use as a daily support wear.
