These 15 ml. glass pipette and bulb droppers feature a straight tip, and will fit appropriately into any of Spark Naturals 15ml glass bottles.
Not sure if you can see it, but the dropper sits crooked when on the bottle. It accidentally tipped over one day and a bunch of my Shield oil leaked out. Any ideas to remedy this issue? Tried another dropper but same thing happens. Tried to capture it in the photo, but not sure you can see it.
