The Endo GRT Case for the Blackberry Torch is light, but most important… it’s durable. AGF’s patented glide rail technology case is made with super slick glide tech resin so your phone opens and closes with ease. This Endo Case is made with a soft, flexible TPU outside, combined with a very durable polycarbonate internal skeleton! AGF’s Endo Case has a polycarbonate internal support structure-providing the utmost protection from every angle. Our GRT case attaches to itself – not your Blackberry Torch – so there’s no need to stress over any scratches. The best part about this case is that it protects your phones slider mechanism from wearing over time.
