I managed to get my hands on a complete set of Krana, Krana Va and Krana Kal on Ebay. Yes, that's right - all eighteen colours in all six varieties. However, I am ashamed to say that I do not have a gun metal, vacuum metal or sterling silver krana.I do not have many krana, but I do have all six purple kraata. I also have the Nike Kraata. This is the translucent orange kraata that comes with the rahkshi shoes, but I got mine separately.
