Some Google Reviews about Jumbo Sized Test Tubes:

Holly Christensen: Ordered 15 test tubes. Very well packaged, quick delivery times, high quality test tubes that feel great. Thanks for the great service!

These giant test tubes are 38x200mm (1.5x8 inch) and made with thick clear borosilicate glass. Thick rims for tight stoppering and unmarked but printable for promotional use. They have very thick walls and are nearly indestructible for displays in stores or trade shows or packaging. Dave Mertz: The large test tubes were perfect for a vase project I wanted to do. The price was right and the shipping was very fast.

I purchased 38x200mm test tubes to replace rain gauge tube that broke & I could not locate any other option local/online that would fit the - apparently - special size for the rain gauge. While I was disappointed the test tubes did not have incremental markings (for rain measurement), since the test tube fit the rain gauge perfectly, I was able to transfer markings from prior/broken tube to the new test tube. Subsequently, able to use the new test tube for my rain gauge.
