Are these tubes metal or plastic?

The tubes are plastics, but they have electric connections to allow the auto focus system works.

they are plastic. What I figured out how to use them I have had a blast with these things. I use them with my stock lens. I went online and found out how to use them properly and I have gotten some very good macro shots although I do have to focus everything in manual I'm enjoying playing with them and experimenting with my photography.

They're made from a hard plastic that can support my Canon 70-200mm f2.8, bust some parts are metal, like the release latches and the autofocus connections.

They are metal (brass), and I recently saw one I put on a frame a year or more ago and it still looks as perfect as it did the day I received it.

They're plastic. I loaded it pretty heavily and the only thing that ever failed was the lousy wall attachments it comes with. Replaced them with molly bolts and this thing was great.

No they are plastic. They work really well! Pay attention to how the old ones are threaded and just do the same.

I think they are plastic, but I've had them almost a year and they are very sturdy and look great.

They are plastic.. I really like them better than the regular pump bottles.

They are plastic. It is kind of thin so be gentle with them. I have made 3 batches with them and they are still holding up.

Plastic... they are just like the ones you would get if you bought a Medela pump.

They look metal and upon further investigation, they are 'metalized plastic'. They look good though and seem to hold up well.

They are metal on the one I ordered. I love it for storing my daughter's shoes. Great space saver !

they are metal tubes, but the metal is kinda flimsy so you need to be careful if you are trying to push it into soil or something. but it did stay standing up for my entire outdoor wedding. :) and the wind was moderate.

Tubes are metal, frames that tubes fit into are plastic and the shelves that lay on top of tubes in frames are metal.

The question isn't as easily answered as I thought it would be. From their appearance to me, I believe the structure of the tubes is metal. They seem heavy enough and they certainly are sturdy. To get a "for sure" answer, you might have to contact Vivitar.

They definitely aren't plastic. I'm not sure if they're stainless steel but they are some kind of shiny, steel-like metal. They're actually pretty sturdy.

The last two tubes I purchased were still in aluminum tubes. I haven't seen them in plastic packaging but that does not mean that it is not available. Only that the sellers that I buy from have the aluminum tubes. Hope I have been some help.

The tubes that I purchased are plastic. I have purchased them twice and both times I have gotten plastic. There are other tubes that are glass however they are a different type, more like a test tube.
