MetMo Gear Train

MetMo's latest creation turns mechanical obsession into something you can feel in your hands. Built around a precision-machined gear system, the tool amplifies input torque by a staggering factor of 16,384—each gear doubling power as it transfers force through the system. CNC-machined for absolute tolerances, it's engineered not just for performance, but for fascination. Even the locking pin becomes part of the experience: remove it, and reassembly is only possible when every gear aligns perfectly, transforming a simple mechanism into a tactile puzzle. It's a celebration of gears, leverage, and mechanical purity—designed to reward patience, precision, and an appreciation for how things truly work.

Nutrafol

Hair loss may be inevitable, but Nutrafol approaches it as a system worth optimizing, not disguising. Built around a whole-body philosophy, the brand's physician-formulated, drug-free supplements target the underlying drivers of thinning hair, including stress, hormones, metabolism, and aging, rather than relying on cosmetic fixes. Its Men 50+ formula reflects that precision, designed specifically for the biological shifts that come with age and clinically tested to support thicker, fuller hair, improved coverage, and reduced shedding in as little as three to six months. Backed by dozens of clinical studies and trusted by dermatologists and healthcare professionals, Nutrafol treats hair growth less like a quick intervention and more like long-term maintenance for a changing system.
