There are the size of a chap stick so they are great for a pure, cosmetic bags or even a clutch purse. You must have a perfume that has spray nozzle which you take off and then place the Travalo on top and then the pump the liquid out into the Travalo. What I do to clean it out is a get a cheap little empty spay bottle from the dollar store and place hot water in it and then you pump that into the empty Travalo and pump it out. Its the best for traveling so that you don't have to take you large perfumes. Doesn't leak so that's a plus.
