Can you use this to refill the travel size as well?

It says that you can but I don’t see how we could. Someone else asked the same thing. This is a travel sized spray for our purse. Maybe when I’m at the end of it I can try to twist off the top but I just got it so that’ll take a while as I rotate between 30 different fragrances between Burberry, Valentino and Dolce and Gabbana. So by then you’ll probably have your answer. Maybe check on YouTube to see if there’s any videos available?
