not sure, sorry :( The website says: "All iPhone 4/4s, 5/5s, 6/6Plus and 7/7Plus available.". S it looks like there is no iPhone 6s. I'd ask them just in case.
iPhone 6s is the 3 x 5 inches option right? Confused over the pricing and the website doesn’t reveal much useful info on this. http://www.printerpix.co.uk/cpg/06/e06/IphoneCover/
