Essential Oil Roller Bottle 144-1 ml COBALT BLUE Glass Micro Mini Roll-on Glass Bottles with Stainless Steel Roller Balls

We only use PURE solid color glass in all of our products. We have Cobalt Blue bottles that are thicker than our amber bottles and can be used with any liquid since the Borosilicate glass can be used. As a side note, gold/white droppers are also available for these bottles. This is a great way to give samples to people you think might be interested in your products. That is a great question. Thank you very much. Customers considering painted glass bottles should be aware that it is not recommended to use them for expensive essential oil or CBD, reports have stated that some have found overspray inside the bottles contaminating the contents. My sincere thanks go out again.
