Inrō
An Inrō ( Japanese 印 籠 , dt. "Sealed container") is a sealed or medicine box from Japan and belongs to the so-called Sagemono ("hanging things").
It consists of different departments stacked on top of each other, which are so precisely worked that they close almost airtight. The top part acts as a lid. Inrō can be made of very hard wood, horn, ivory or ceramic. Originally the Inrō was designed as a container for messages, but over time it was used to store coins, personal seals or medicine for traveling. It was mainly used by men, whose clothes, unlike those of women, mostly had no sleeve pockets. To do this, it was attached to the obi with the cord and secured with the netsuke .
