Make lid removal hassle-free with the Fermonster Lid Opener. Specifically designed for use with Fermonster carboys, this tool ensures you can easily unscrew lids without disturbing the sediment at the bottom of your fermenter.
Made from HDPE, this opener is BPA-free, food-grade, and built to last. Note: This tool is not recommended for tightening the lid as the seal is achieved through the O-ring, not by over-tightening.
