Tubes pieces?

[Yzalirk]

I never knew LEGO came out with tube like pieces. Where could I find them on BrickLink? They were used in these pictures I found off Google.

Wow, I've seen these tubes used inside trees (to support towers of 1x1 rounds or 2 x 2 rounds) but I'd never thought to use them as the trunk themselves. Then again, I didn't know they came in brown. Brilliant idea.

The Pet Shop and Grand Emporium come with black ones. You could look up the part number for them on BrickLink and then search for brown ones.

They come in differant lengths too, they are quite useful, I never thaught of them to make trees stems though, got to try that.
