This product is a 6" Czech Art Deco satin glass vase with confetti spatter design. It features a multicolor Bohemian pattern, hand-blown production technique, and glossy finish typical of early 20th-century Art Deco style. The vase is unmarked and unsigned, making it a unique handmade piece suitable for decorative purposes in any art-themed setting.  Typically, this type of glass also goes by the name "end of day" glass.  This was possibly made by Kralik, but since unsigned as most of their glass was, I can't be 100% positive.  Other than being unable to pin down the exact maker, it definitely screams Art Deco Czech/Bohemian glass circa late 1920's to early 1940's - the era when this glass was popular.  Probably came with a paper label that has long since gone missing.
