Nayab is the Chinese producer of lowend animal figures (rather toys than collectibles). Nayab´s figures are very different in their size and quality, they are made from hollow plast (in most cases from 3 pieces). Two years ago I bought such figures in the souvenirs shop in Pilsen ZOO (SW Bohemia). They represent lesser-known animal species, are average quality with no company branding. They were pretty cheap. Better one image than thousands of words, please look to the attached image.
As far as I know today are unbranded Nayab´s figures available in Czech Republic in "Kaufland" stores but by far not in the entire product range.
