Small enough to fit in any purse or pocket
I have NO clue if you could fly with this. If you check it, sure, but probably not in a carry on as it is a spray bottle. I have to mail these all over the country. I don't know if they are going to leak. I do hope not. The top didn't seem to want to fit well. Only time will tell. If they don't leak, then they are good little spray bottles. I'll let you know after I send them out and hear from my friends.
