Sorry I dont have a pic, but maybe I can help. They are probably the same size as the Wal-Mart ones. About the same size as a Windex bottle, just a bit wider on the bottom.
HOWEVER!!!! Trust me...during summer time in WDW they are your best friend!! You wouldn't even think twice about carrying them around.
We had purchased the
Walmart ones...but the blades on them break pretty easily...They do not hold up to packing and lugging around the parks very well. I also found that it goes thru batteries...like water.
Last year in Epcot it was a 103 degrees one day...I broke down and bought a few......They WERE WORTH EVERY PENNY!!!!! The greatest DISNEY SOUVINEAR! EVER EVER EVER! Pretty Sturdy & gives much needed relief!
