Well made
These aluminum tubes are well made and are just what I needed to fit into the little hole at the end of the spray nozzle for yellow jacket spray

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.

It is grate
They are made of copper. The 3/16” O.D. Pipe fits in the hole I need it to nice and tight, like O.J.s glove fit. It arrived on early, which means to me they did not dither at the facility, and that it was in stock in the United States of America.

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

Perfect.
Good aluminum tubing. I made 2 sets of miniature wind chimes, Shipping was so-so, but I was not in a big hurry. I would recommend this aluminum tubing, the measurements are 100%. Thanks, Amazon. -Bud

Y'all've ever heard of Singing Straws? They're a tool designed for singers to help lighten vocal cord mass, and are literally 3 stainless steel straws with differing diameters...and they cost NINETY-FIVE DOLLARS. You can use disposable ones, but they're no longer available in my town, so I needed an alternative. So i grabbed a pack of these, washed em, halved the 4 sizes I wanted to use for practice and bingo bongo, a full set of singing straws. Even if I threw out the rest of the pack (im keeping for craft use), each would still only cost 2.50. Highly recommend as an alternative to the inordinately overpriced brand-name ones lol.

Absolutely perfect for my project needs. And they came just in time. I’m mad over the ridiculous tariffs on aluminum are now in effect between Canada and the US. It’s ridiculous.
