Featured Carved Bone or Ivory 1-Case Inro with Rabbits: Chinese?

It's 2 7/16" long, 1 7/16" wide; the agate ojime is ~3/8" diameter. It weighs ~2 1/2 oz. It was a recent gift from an old friend, an' I'm tickled to have it...but thought to offer it for your opinions an' observations.
These are several of the reasons I lean toward Chinese vs Japanese origin:
It is unsigned (I have looked, carefully).
There is no Netsuke.
The decorative knot in the cord doesn't seem Japanese to me.
The pair of rabbits, in 2 places, look somehow more like a Chinese theme, but that's a weak assumption.
And finally the dark staining on the inside surfaces are 'out-of-place', in my (limited) experience with Inros from Japan.
There is the faintest odor there, which may be of tobacco...an' maybe not.
The long cord may be for hanging around the neck, tho' that is not customary with Japanese Inros.
Thanks for lookin'!

 

I'd say Chinese too, and not partiuclarly old.

 

That's my sense of the age, too...maybe as early as the 1st couple decades 20th C.

 

I'd say more like the 1980s. It looks like what used to be in Pier One when they still sold good stuff.

 

All that bamboo definitely says Chinese to me.

 

Bone, not ivory.

 

HA!!!! Is Pier One even around anymore?????!!!!

 

I doubt it, seriously.

 

They went online only. The website is still active, but all of the good stuff is 30 years gone.

 

I'm with the others, Chinese, bone, 1980-2000ish. And cute.
