Review on 🌸 60ml Large Flower Water Tubes with Tube Rack - 4" Clear Plastic Floral Tubes Vials with Caps for Better Flower Arrangements and Milkweed Stem Cuttings - MeiMeiDa Floral Craft Supply by Kristen Reid

These tubes are too big to fit in the plastic test tube racks I bought from both Revain and my butterfly farm supplier. I didn't realize it until I threw the packaging away. If you're growing butterflies in a plastic test tube rack, don't buy these! These are really good tubes. I would give them five stars if I could use them. It would be great if a new post with larger holes was available.
