Sadhu Board with Aluminum Nails, 12mm (0.47 in) – For Advanced | Tengry

The TENGRY Sadhu board with 12 mm aluminum nails is our most intense model — designed for experienced practitioners who have already mastered 8 mm or 10 mm boards and are ready for a deeper challenge. The wider nail spacing concentrates pressure on fewer points, for a stronger acupressure experience in every session.

Who is this board for? Practitioners who already stand comfortably on 8 mm or 10 mm boards. The 12 mm spacing puts deeper, more concentrated pressure on each nail — a more demanding practice that trains focus and patience. Individual experience varies with body condition, balance and pain tolerance.

Custom-made nails. These are not standard construction nails: they are designed and produced exclusively for TENGRY Sadhu boards and shaped for standing-on-nails practice.

How to practice: begin with short sessions and increase the time gradually as your body adapts. Socks soften the intensity. Progress at your own pace.

Two interlocking boards fit neatly into the velvet case for travel, retreats or daily practice at home.
