Safe to use - The extension rod design provides stable support during experiments, reducing the risk of spills and accidents. 3 finger design - The wrapped fingers grip the cup firmly to prevent slipping or falling. - The finger opening is adjustable to fit different cup sizes for versatile use. Delicate design - Covered contact points prevent scratching of objects being held. - The adjustable clamp base attaches easily to a table edge for quick, tool-free setup. Sturdy and durable finish - The surface coating is rust-proof and corrosion resistant for long-term reliability. 2-3 use scenarios - In a science classroom during experiments, use to hold cups steady while adding liquids or observing reactions. - In a home or school laboratory, stabilize cups for precise measurements and data collection without needing to hold them manually. - In a workshop or maker space, attach to a table edge to provide hands-free stabilization during mixing, testing, or demonstrations.
