Upgrade your gear's look and feel with these slick aluminum knobs! You get 24 pieces total – 8 in black, 8 in gold, and 8 in silver – all with a knurled texture for a solid, non-slip grip. They fit standard 5.7mm knurled shafts, so they're perfect for replacing worn or boring knobs on synthesizers, amplifiers, mixers, effect pedals, or DIY audio projects. Made from lightweight but durable aluminum alloy, they resist corrosion and won't fade over time. Installation is a breeze: just press them onto the shaft, no tools needed. The medium size (about 0.57 x 0.64 inches) feels comfortable, and they come in a handy storage box to keep them organized. Whether you're tweaking tone, adjusting volume, or just want a more professional look, these knobs are a simple and affordable upgrade. Give your equipment a fresh, custom vibe!
