Hi,
That is definitely Kokusai. It is said on the box.
This rounds been using for Kokusai revolver for long time by the time Kokusai release "new concept model", a HW version of revolver with smaller cylinder insert so that you can use dummy rounds from Malburryfield. For those who are interested in "new concept model", I can post a cylinder close up.
cheers,
