Stainless steel opener cap suitable to all Ø 70 mm regular mouth jars (Four Seasons, Mason Jars etc.). Transform your jar into a multi-functional container with the opener cap, perfect for uncorking glass bottles and retaining the caps. Keep it on the table to have a bottle opener always at hand. The cap has on the top an opener and a hole in which you can insert the corks, without opening the jar. The stainless steel opener cap is hygienic and does not retain odors and does not alter the flavor of foods. You can safely wash it in a dishwasher and reuse it several times.
