Hi Detief, I have done some searching for information on Taji and up to yet have not found a great deal on boxes that are the same as mine but I did find tubular wooden boxes which when closed looked very similar but when open the blades were located in holes drilled in the circular base, the outside tube being lifted off to reveal them. The base did not have a central dividing pillar and was not connected to the lid as mine are. These were said to be from Sulawesi so I wonder if that's where mine come from.
Regards
Miguel
