beautiful green bottles leaked [SEP] bottles do leaked when shaken putting a rubber band at the neck of the bottle did not improve much so if you must shake the bottle shake it sidewaysnice fine mistupdate added one star company reps elena lisa contacted us gist of their msg was they need positive reviews for a successful business we absolutely agree and they mentioned they are seeking a manufacturing plant that gives quality bottles not their words but the thoughts conveyed they also offered a refund which we haven t received it woulda been much more effective had they fix the problem and sent no leak bottles for a positive review in any case it s still usable and keep in mind you will read about leaking bottles from other vendors too go ahead and purchase if their price is right and if there are problems return them
