Review on 🔧 Efficient 4-Way Tire Valve Stem Core Tool - Cal-Hawk (4 Pack) by Kevin Nelson

Worked well. Well done. Universal. Use for mountain bikes. Works ONLY with Schrader valves (common for car tires). Not for Presta (btw, not all Presta valve stems are removable). Video on Youtube for those who want to learn something new with their own hands. Useful when you need to remove the valve core to add mucus to the inner tube. We have goat heads/pierced vines in our area of the country. Can walk through many hoops that have no pads or slime.
