Need a bunch of small containers for crafts, science projects, or party favors? This Flutesan set gives you 200 clear plastic test tubes, each about 16mm wide and 100mm tall (that’s 10ml volume). They come with colorful snap-on caps that seal tightly to keep liquids, powders, or tiny items from spilling. The tubes are made from sturdy polystyrene—they won’t shatter like glass and are reusable. Great for school experiments, growing small plants, storing beads or spices, or even as cute candy holders at a Halloween or science-themed party. You can also use them for DIY hummingbird feeders, bath salts, or mini terrariums. They’re easy to label, stack, and store. At 200 pieces, you’ll have plenty to share or use for multiple projects. Just hand wash gently—they’re not dishwasher safe. A super versatile and affordable kit for teachers, parents, crafters, or anyone who loves organized small storage.
