After filling your container, align the top with the opening and press or twist it into place, depending on the closure style. Ensure the lid is fully secured to prevent leaks, spills, or fragrance loss, then wipe away any product from the rim for a clean seal. Test the closure for a snug fit before labeling or storing your finished product. Please note, the Gold Lid - 70mm only fits the 9 oz Straight Sided Jar.
