very cute little square glass bottle . glass dropper has a gold colored half moon on top. It can be used however liquid only fits in the tiny cylinder in the middle of the bottle Im guessing its about 15-20 ml. I had bought it thinking I could use the entire square glass for liquid. see photos for better Idea of what I mean. would be great for an oil perfume only used on special occasions. will throw in a beautiful dark purple velvet bag as well.
