These are classic dental glass bottles that have been manufactured by the factory in Tokyo since Taisho era (around 1912). Each bottle is made by skilled craftsmen by hand using the traditional technique. The mouth part is carefully cut with an industrial diamond, so that the liquid does not leak and the lid closes snugly.
