Small O.D. Glass Tube for Glow Stick

This single-end sealed small outer diameter glass tube is a dedicated internal isolation part for mini and lightweight glow stick products. It is designed to store internal chemical liquid and isolate two different reactive materials to prevent premature reaction before use. After completing liquid filling and secondary sealing, the tube can be perfectly assembled into small-sized glow sticks. When bending the finished product, the glass tube ruptures smoothly to blend the internal solutions and create even and soft luminescence.
