As far as we know, the Astrojax Weave is the first product to combine hand-crafted textiles with precision-tooled metal and injection-molded plastic. Also, as far as we know, we are the only company to produce a crocheted item with a size tolerance of +/- 1 mm! To properly interface the crochet, plastic, and metal necessitates a level of precision previously unheard of for crochet, requiring extensive training of our craftspeople and stringent quality control to bring you the best version of Astrojax yet!
