wāk Heads Ravi: A Heritage Rooted in Pakistan. Crafted from the Ravi strain of miswak, grown and harvested in Pakistan, these biodegradable heads bring ancient oral care into your daily rhythm. The Ravi strain is prized for its natural freshness and balanced texture, making it ideal for everyday use. Each pouch includes a biodegradable sampler stick, allowing anyone to experience wāk heads on the go—even without owning a wāk Stick. This makes the pouch both a refill pack for wāk Stick users, as well as a standalone pack (with the sampler stick) for on-the-go ease or for first-timers to the ritual. Natural. Portable. Timeless.
