Does otterbox make replacement screen protectors?
Otterbox does not sell screen protector replacements. You could however try the one by Boxwave.com. it matches it and even looks a better make up for the original Otterbox screen.
No they don't but if you call them@ 888-695-8820 they will tell you how to return yours for a free replacement I did it it took 8 days between the time I sent it and received the new one they were very helpful and easy to deal with.
