1"OD 3/4"ID 1/8" walled Trans Red Polycarbonate tube 40" long.
This is considered a thick walled tube.
The remaining tubes we have, have a slight bend in them. You can get this out by supporting them by the ends and working it out over time but just know they will come with a slight bend.
Awesome red blade!
Used this on a maglite build. I used a quad wrap of blade film, a bullet tip, and I used the colored disc (hand filed to fit the bottom of the bullet tip). This gave me an awesome blade that looks like red chrome until you turn it on then it really lights up with a tip that closely matched the blade. So far it is surviving some rough play from an 8 year old Star Wars fan.
