Our specially designed brushes are the ideal solution for cleaning holds in bouldering gyms and at competitions. The stick is made of aluminum—flexible yet extremely durable—ensuring long-lasting performance.Two brush sizes are available: Midnight (17 × 4.5 cm) for larger slopers, and Lightning (8.5 × 3 cm) for small crimps and pockets. Both are designed for intensive use in gym settings. Natural boar hair bristles, developed through extensive research, provide optimal cleaning efficiency.The brushes are securely fixed with bolts, allowing easy replacement or extended lifespan by mounting them in reverse once one side wears out. Discounts are available for orders of 5 or more pieces.
