Babushka Jar

A large jar (cylindrical, 1ft^3) lined with faint symbols engraved onto the glass. When opened, empty and turned upside down it manifests a slightly smaller jar that slides out, when this next jar is similarly turned upside down it manifests a jar smaller still and so on, down to a vial. The Babushka Jar can support 15 smaller jars at once after which no more jars will manifest. If any of the manifested jars are broken or returned to a larger jar they vanish and don't count toward the total manifested
