What material are the stoppers made of? Are they just rubber stoppers?

They're ruber stoppers for the erlynmeijer flask and the upper distillation part but they are cork stoppers for the condenser.

Hi Max. The stopper is crystal. We absolutely love this set and use it frequently.

They are made of acrylic. I used them and they looked great. They did the job perfectly.

They are made of a soft flexible plastic or rubber. Very cute and worth the price.

They appear to be made of medium soft rubber, and they're hollow. They seem to work very well.

They're made out of the same plastic as regular plastic hangers. I haven't had any issues with them.

I think they're rubber. I wouldn't purchase this again - the arm really doesn't push hard enough to make tearing easier, and mine was rusted within 6 months or so.

No, there is no rubber or plastic around stopper, however crystal stopper is tight enough to hold aroma of whisky.

Yes. They are made of rubber, just like a rubber wristband on a sports watch.

No stoppers included but I haven't had any fall over as they have a flat bottom surface. They work really well.

They are brass, however the rubber stopper sticks in the closed position. We went to Lowes and bought a brass ball valve for $5.00 to replace it. Other than that, we like the barrels. We did let the company know that we were unhappy with the cheap valve.

The stopper does not have rubber on it but it creates a good seal considering its a glass stopper. I hope that helps.

They seem to be made out of a heavy duty plastic - there is no recycle icon or number on any of the bottoms-hope this helps!

They are aluminum and have a rubber striking surface where the primer would be. These handle nicely, I like 'em much better than plastic & spring caps.

They are plastic but almost feel rubberized, I expect them to last as long as the rest of the wagon, it's very well made. My new phew recently got a lower priced wagon about 80.00, and those tires seem like they might crack over time or either over exposure to the sun, these don't seem that way at all. ;-)

They are made of a flexible plastic (called TPU). They won't break if you drop them like hard plastic and do not have the gripping quality that silicone cases would have.

I don't have the packaging to tell you exactly what they are made of, but they are definitely flexible plastic. My granddaughter loves them.
