This is a Storm Glass, popular as a stylish interior decoration. It's a cute cube shape and comes with a wooden base. Main body size: Approximately 6 x 6 x 6 cm Base size: Approximately 6.4 x 6.4 x 1.8 cm • Crystals inside the glass change with changes in temperature and atmospheric pressure. • Recommended as an interior decoration or as an observation item for children's learning. I bought it new and stored it in its box without displaying it much, so it's in good condition. It is a used item, so please understand this before purchasing. It will be shipped in its original box.
