Transform your Stache Flex into a complete dry-herb rig with the Flex Grynder Top. This modular attachment swaps in place of your Flex’s torch top to give you a smooth, consistent grind on the go. Its patented micro‑rounded teeth gently separate sticky herbs without tearing them, preserving terpenes and potency. The ergonomic lid and precision machining deliver effortless turning, while the durable anodized aluminum construction matches the Flex’s sleek aesthetic. Pair with our glass top and water tool adapter for the ultimate all‑in‑one experience.
