Collection: 30ml Essential Oils

Mayjam's 30ml essential oils are the everyday size — big enough to last through weeks of daily diffusing, small enough to stay fresh before you reach the bottom. If you've found the scents you love and use them regularly, this is the size that keeps up.

Each 30ml bottle holds 100% pure oil, steam-distilled or cold-pressed from natural botanicals, with no fillers, dilutants, or synthetics. It's a comfortable middle ground between the 10ml trial size and the 100ml value bottle.

Who it's for: the regular diffuser user who runs a scent most evenings, the home blender making roller bottles and room sprays, and anyone settling into a daily aromatherapy ritual. A 30ml bottle holds around 600 drops — months of use at a few drops per session.

Build a small rotation: a calming oil for nights, an uplifting one for mornings, and a fresh, clearing scent for cleaning days. Always dilute with a carrier oil before skin contact, and store away from direct sunlight to keep each oil at its best. Browse our 30ml essential oils for the size that fits real, everyday use.
