Manufactured from highly translucent and semi-rigid polyethylene (PE) with walls and crush-resistant corners. Colored body and caps enables fast, easy and practical identification of bottle content. Round neck form allows un-restricted liquid flow-out without leaving any residue at the bottle neck. Flexible delivery tube guarantees a fine and straight flow with an application of a slight pressure on the body. “Goose neck” design of the delivery tube guarantees easy and precise reaching to the flask corners. Tip of the delivery tube can be cut to increase the flow rate.
