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.\n\nCustom-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.\n\nHow to practice: begin with short sessions and increase the time gradually as your body adapts. Socks soften the intensity. Progress at your own pace.\n\nTwo interlocking boards fit neatly into the velvet case for travel, retreats or daily practice at home.\n\nShipping: free to the United States, Canada, Japan and Europe.
