I found the perfect "rack" for my cookie-sprinkle-filled test tubes! Remember when I was on the hunt for a way to display them? I was shopping at Michaels craft store and noticed that they sell medium-size clear acrylic boxes (near the unfinished wood and tin containers). I bought 2 boxes and took the lids off. The bottom half of the box makes the perfect container for my sprinkles.
The test tubes are safe and secure, all while showcasing the beautiful colors and textures of the sprinkles. I can leave this on the kitchen counter and get inspired to bake.
