never heard of this film but it is a nice one!
I think it's a single layer film from croatia. Very fine grain if you go for the recommended development process. If not, it turns out much more grainy.
Like you can see here: www.lomography.com/homes/d_i_d/albums/04-09_efke
There is also a 25ISO film of that brand, but i never tried that.
