I am picturing in my head, you sitting with your turtles feeding them with chopsticks. I would think to use them as markers, if you are going to write the name of the plants on it, you would need to write very small. Often times I just find I cannot throw away things that are perfectly good. I have a friend who owns a Chinese resturant and have never asked what they do with the used chopsticks, I fear they would throw them away and then i would have to take them and find a use for them. So I don't ask.
