K&S engineering is exact
Accurate, perfect telescoping fit. Good quality brass metal.

Great for Candle making.
The brass tubing works perfect. I use them in my candle making process. Placing the wicks was a pain before this. Great for the 8 inch candle glass you buy at the Dollar store. Well worth it.

Tubular!
Very tubular, in fact, grown men burst into tears when they behold the tubularity of these shiny tubes.

American made!
very high quality with perfect slip fit from one size to the next. Used 1 tube to rebuild/repair center bottom X-frame on grandson's Traxxas car that was run over by a real car! The bright brass looks really sharp on the bottom of his car...sorry I don't have a photo. Quality the same as it was 50+ years ago.

Very useful for metal projects
I bought these for a metalsmithing project. I had not bought them for making hinges, but found the twelve fit nicely one within another. This will make them quite useful for making hinges in future projects. Very good quality (as K & S products consistently are).

telescopic tubing
very straight and nicely finished, but I only received 10 rather than 12. cannot tell which are missing as all measuring tools are locked up at work

Good stuff!!
Used the smallest of the tubes to make some mosaic pins for a knife handle. watched a couple of YouTube videos and made my own. Hope to find a use for the larger sizes before I have to buy more...grin. A lanyard hole or two might be the ticket.

At the present moment I have not used any of the tubing. I have used K&S products previously and found them to be of a high quality. I highly recommend them. The item arrived 1 day erlier than predicted.

Worked perfect for repairing the over flow brass tube on a motorcycle carburetor.

These tubes snugly and smoothly slide into one another like they should.
