A minimalist concrete flower vase with clear giant sized test tubes is perfect for single stems, hydroponic cuttings, or modern industrial décor.
This modern concrete flower vase combines the raw strength of cast concrete with the clean clarity of borosilicate glass test tubes. The result is a striking, minimalist centerpiece that highlights single stems, propagated cuttings, or hydroponic herbs. Each 38x200mm (1.5"x8") glass tube lifts easily from the concrete base for cleaning or refilling, making it a reusable and sustainable alternative to traditional vases. Ideal for modern homes, cafés, studios, or offices, this design adds subtle texture while keeping the focus on the plant. Put them on a windowsill for bright, indirect sunlight to enhance growth. Or use as kitchen, living room or home office decor where their modern look will appear to the boho inclined.

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.
