These 26mm crown caps fit standard, pry-off beer bottles. Do not use twist-off bottles. The oxygen-scavenging liner helps reduce oxidation and staling. 144 per bag.
For best results, do not use an oxygen based cleaner or sanitizer such as One-Step or Easy Clean. A quick dip in Star San or Iodophor is sufficient. Do not soak or boil. Use immediately after sanitizing. The oxygen scavenging property in the liner is activated when wet. Do not save caps for later use once they have been exposed to liquid.
