This novel Christmas decoration was crafted from recycled pine, sliced, drilled & made into a wall hanging test tube planter. Many thanks to Jim Caulfield of Rustic Magic in PA for this image.
Note the use of three 1x4" (25x100mm) glass test tubes flower vases in this design. Their extra thick rims are ideal for making hanging plant/flower vases. Test tube capacity is ~30mL/1.1 fl. oz.
This size test tube is also available with these options:
25x100mm tubes have rounded bottoms & require support to stand upright
Completely unmarked for decorative use
25mm (~1"); 100mm (~4")
Tube capacity/volume is ~30mL/1.1 fl. oz
Note: Test tube diameter and length is nominal; there can be a variance of as much as +/- 0.5mm. We cannot guarantee they will fit test tube racks or stoppers we don't supply.

Excellent quality glass tubes. I am using them in wrought metal flower holders. They were a little bigger than what I was replacing but that was a measuring error on my part. Even so, they fit and look nice. Well packaged, safely and promptly delivered.

These test tubes are exactly what I needed to fit in my vase. This is the only company I found that was able to sell them individually and at a reasonable price. I purchased 10 or so and all arrived well packaged and good quality. Thank you so much!
