Black Strong & Flexible: Black nylon plastic with a matte finish and slight grainy feel.
About this Product
Taken from the Doctor's Name glyph, the case is a perfect fit for your iPhone.
Note there's a possible 'snag risk' from the rings that go outside the perimeter of the case - they're a bit fragile being only 0.9mmx1.4mm. But they are cool!
The black nylon material is coarse to the touch but using it with my own iPhone caused no marking of the metal rear over the test period, but I recommend for prolonged use using a cheap screen protector on the rear of the phone to eliminate any chance of the case being inadvertently marked.
