appropriately sized bottles for travel [SEP] i don t like to travel with the original bottles of shampoo body wash etc they are huge and would take up my whole suitcase this set of bottles are great for holding just enough to last the trip there are three cc the maximum amount per bottle for carry on spray bottles also there are three cc pump bottles each is made of hard plastic and inches tall they fit very well into a purse or cosmetic bagi put shampoo conditioner body wash and hand sanitizer in them they are clear so tsa shouldn t have a problem with it when screening at the airport the pump and spray are easy to operate one word of caution on the pumps the pump attachment does not lock so i recommend saving the little clip that came with the bottle to keep the pump in a locked position in summary these are good quality pumps and spray bottles for a great price
