Glass Test TubesJumbo 41 X 225mm with Cork Stoppers, Pack of 5

These worked great for my project.

Cool planters

Homebrew beer yeast tubes! I make a large yeast starter for homebrew yeast, decant most of the liquid off after it settles, then divide it up into these test tubes. Now that high-dollar yeast can be used in several beers without trying to re-capture it after fermentation. Perfect for homebrew yeast! You have to replace the cork stoppers, or can just put a zippy bag over the top with a rubber band around it. Either way, great tubes. They hold 250 ml or 8.5 oz. Perfect size!

Good

My fault. They're just a little too big. Otherwise 5 stars.

very good product

I actually use them as inserts for wood turned flower vases

Love these. Better than expected.
