The VialCase Round Screw-Top Vial Jar keeps your vials upright, separated and sealed in a sturdy twist-lock jar - each vial stands in its own round pocket so nothing rattles or tips, and the threaded lid screws down over the tops so the jar can ride in a bag, a drawer or the fridge door.
Key Features
- Individual round pocket for every vial - vials stand upright and never touch each other
- Real screw thread: the lid twists on and stays on, no hinges or latches to snap off
- Soft round barrel with grip flutes and a knurled lid - easy to open with wet or cold hands
- Compact: sizes from a single vial up to 10 vials
- Safe for cold storage in the refrigerator
- Available in Black, RGB Metallic, Cyber Green, Galaxy Purple, Purple and Cobalt Blue
