Blue Oxygen Barrier Bottle Caps
144 count package
Top Quality, 26mm Bottle Caps with a PVC Free, Oxygen Barrier Liner.
These will fit standard crown cap beer bottles. 
These will not work with twist off bottles or Belgian style bottles.
Use a no-rinse sanitizer like Star San or Easy Clean to sanitize bottle caps before use. 
Never boil your bottle caps to sanitize them as this will warp the inside liner and prevent a good seal.
