I purchased this at a local antique flea market over a decade ago. There is a marking on the bottom, but I don't remember the specific manufacturer or product information, so it's unknown. Please be aware of this. ★ There are two small scratches on the outside, on the bottom. As shown in the images, the scratch on the left appears to be an indentation from the beginning, and the scratch on the right looks like a small chip from being bumped. ★ There is some dirt on the inside bottom of the vase. ★ There are air bubbles and color unevenness typical of old glass products. ※ This is a very old item, so please consider purchasing if you understand the condition.
