8 oz. squeeze bottle is 2.25" in diameter and 5.5" tall, so it fits into your palm nicely. Unlike the standard squeeze bottle, the tip points downward, and comes with a 1 mm. output hole. The spout can be cut back if you want a larger diameter (which you'll need with sauces).
This allows you to very finely control the output and the detail with your hand in a more natural position (and not blocking your normal line-of-sight).
You should use a standard bottle (not this one) for generic shapes and large deposits of sauce. Use THIS bottle only to finish your art with very fine detail. It's very good for making fine dots.
