This is a bottle cap compatible with any major plastic Bottle brand. But of course following the series of pointless-prints, we had to make this so useless. It has mesh holes at the top to insure a maximum emount of leaking on you or in your bag. And don’t even try to be liken (well this is perfect, I use this as my watering can) but to that I say good Luck. With cutting edge science, our team has installed two slots, polar to each other to make an unsteady and unpractical flow of water and potentially adding more leakyness. Have fun
