This is a neat perfume bottle! It measures 2 1/8” tall – the perfect size to fill with your favorite perfume and tuck into an evening bag. The bottom of the bottle has an impressed number 4 but I could find no manufacturer identification. The little bottle fits inside the metal case and it may come out, I don’t know because it is a very snug fit. The bottle has 2 small faux pearls inside and they were in there when I purchased this item several years ago.
