Why copper bullet nails? Copper is naturally antimicrobial and corrosion-resistant. The bullet shape gives a broader, more even contact surface, so the sensation stays consistent from session to session. In Eastern wellness traditions copper is associated with grounding and energy flow.

How to practice: start with socks for a gentler feel and gradually progress to barefoot. The 10 mm spacing is our most popular choice — demanding enough to hold your attention, accessible enough for most people. Begin with a few seconds and add a little time each day.

Each board carries engraved artwork on both sides with a unique natural wood grain, so no two are identical. Two interlocking boards fit neatly into the velvet case for storage and travel.
