Sup /toy/ I need your help.

I need for a different project durable plastic cylinders. Like the lego light saber blades. Only maybe a little shorter.

Here is the problem I have no idea what is the name of these things.

I got this
https://www.brickowl.com/catalog/lego-black-bar-1-x-3-3l-17715-87994

and this
https://www.brickowl.com/catalog/lego-bar-1-x-3-3l-17715-87994

However the official lego website is a bitch and gives me nothing
https://www.lego.com/en-us/pick-and-build/pick-a-brick?query=3L&page=1&includeOutOfStock=true&sku=

Lego bars fails to give any result same for copy pasting all the random numbers I copy and past from brickowl ....

WTF is the name of this crapsince I liek to brows them and arguably get
>one that is not in clear plastic
>Not black
>Not red
I was thinking blue or orange in mat non glossy.

Only what the living fuck is the name of these things ? I od not care if I need to copy past a long string of numbers.

I can find this
>light saber blade
