Choose-a-Color Bottle Neck Rings
Slip these rings onto bottles to color code their contents. They’re designed for standard GL45 bottles, but they fit any neck with an OD between 1 3/4" and 2 1/2". Made from silicone, these rings are flexible enough to stretch over bulky caps. A pull tab makes them easy to remove, even if you’re wearing gloves.
