One of the problems airline products face is leakage. It happens because of the pressure differential when the plane flys at high altitudes. In order to solve this problem for our customers, COPCO launches this series of spray bottles, which could stand up against such rigorous circumstances. Bottles available in 15ml, 20ml and 30ml. We could also offer only the mist sprayers, to match your own bottles. 2 neck sizes are available, 18/410 and 18/415. 3 Closure options: smooth, ribbed and metal. Feel free to contact us to find out more.
