Science enthusiasts, teachers, and DIYers - this plastic test tube rack is way more useful than you might think! Measuring 5.91x5.91x2.17 inches with 100 holes, it's perfect for organizing test tubes in labs, classrooms, or even for creative projects at home. The blue plastic construction is durable yet lightweight, and the detachable design makes storage super easy when you're not using it. Great for holding lip balm tubes during DIY projects, organizing small craft supplies like beads, or even for mixing drinks at parties (how cool would test tube shots look?). The two-layer design maximizes space without being bulky. Whether you're a science teacher setting up classroom experiments, a jewelry maker organizing beads, or someone who just loves organized spaces, this rack keeps everything upright and accessible. It's reusable and easy to clean - just wipe down between uses. Way more fun and practical than leaving test tubes rolling around on your work surface!
