The box is the antique true Casket shape and is about 5" long x 3" across, and about 3 high. One of the best I have found as these blue casket shapes are very scarce. There are wear scratches on the base, tarnish to the metal, and gaps in the sealant that secures the metal to the glass. It is not loose in any way.
The opaline casket is not signed.
