This is a small, soft, solid, semi-shiny line.

Can be used for real life 9mm spark plug wires. They would drape like the real thing.

It's the perfect size for those small injector lines to the manifold and injector hat.

It can bend at a sharp angle without kinking.

This soft line equals the following equivalent 1:1 size at each scale.
1/25 scale = 3/8"
1/16 scale = 1/4"
1/12 scale =3/16"
1/8 scale  =  1/8"

Typical uses are small fuel lines, or other transfer lines as needed.  
This soft black line is easy to bend and shape to your installation. 

Each package contains one coil of .016" x 18" black flexible line.
