Here are some actual drumsticks. They are .3ds format so just import them into Poser. You can save them as a prop if you want by going to Props library and resaving them there.

Daz also has a marching drum with drum sticks. Not sure if the drumsticks are separate, but I would think they would be.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
