Yoga ball owners, this little tool is a game-changer! The Kofun air stopper and puller set makes inflating and deflating your exercise balls so much easier. Made from durable plastic that won't break on you mid-use. The air stopper measures about 5.1cm while the puller is 6.8x2.5cm - perfect sizes for handling those tricky valve plugs. Choose from different set options depending on how many you need - 1 stopper + 1 puller, 2+1, or 3+2 configurations. Seriously, if you've ever struggled to get the plug out of your yoga ball or fitness equipment, this tool eliminates the frustration. Works great with jump horse horn balls and other inflatable exercise gear too. The design is simple but effective - just insert and pull without damaging your equipment. No more broken nails or searching for random objects to pry out stuck plugs. The white color makes it easy to spot in your gym bag among all your other gear. Considering how affordable this set is, it's totally worth it to avoid the headache of dealing with stubborn air valves. Keep one with your exercise equipment and thank yourself later when inflation time comes around. Your yoga practice just got way less frustrating!
