It kind of looks like a rocket or a torpedo, with a nice sized base for added safety. It's sized fairy nice for not being too big for beginners, nor too small for advanced users. I would travel with this toy even though it's not discreet looking. It's just the right size to carry with you. It is 3 1/2 inches in height, 1 1/2 inches in diameter, and 4 1/2 inches in circumference. The base is 2 1/2 inches wide, with the insertable length being 2 1/2 inches.
