Premium Non-spill Bottle Caps - Quantity of 50
These caps work perfectly for anyone re-filling their water cooler bottles in your home or office.  These are identical caps to ones that bottling facilities use when packaging new water bottles, and will save a ton of money over using a water delivery service.  Simply remove the old cap, refill the bottle, and snap on the new cap to create an air-tight seal and create a sterile environment for crystal-clear water storage.
