These 1/3 oz (10 ml) Black frosted glass bottles with plastic rollers and black caps are sold in a pack of 5 bottles, rollers, & caps. They are great for dispensing essential oils and blends.
You can use a plastic pipette or glass dropper to fill the bottle. After you have added your oils to the bottle make sure to press firmly down on the roller, as this will help avoid leakage. Bottles containing oils or liquid should be stored and transported upright to prevent leakage.
