For those of you looking for a glass dropper that has the rubber nipple on it, please be advised that if left more than a couple of months the rubber on the dropper will melt. I got mine, some time ago, at the Pharmacy at Walmart, and the first year I left it in a zip lock bag over the winter, and it melted the rubber nipple. I use mine, then after a while pour the LGO into another bottle. If you leave the LGO in the dropper, it will melt the rubber tip.
