Review on ZHSMS Valve Core Tool Set: 20Pcs Cores, 10Pcs Caps, 4-Way Tool – Professional Tire Repair & Maintenance Kit by Javarie Malick

For those who work in the automotive industry and have never changed tires or valves this kit was perfect. I had to change the tires on my tractor and the valves to be on the safe side. I read the reviews and bought this set and it worked. It has everything you need and since then I've been using it on bikes too. Worth the price
