Is it safe to not put a case on my iphone 5?

I own a black iphone 5 and i don't really want a case on it. But i'm worried about it breaking or scratching. I go to highschool. It will be in my pocket all day. I may bump it on a bench every now and then. Is it safe to do this or is it better to be safe then sorry. No one in my school will hit it or anything the school isn't that bad.

An example of what it might be after an accident…

  • What's a safe iphone case besides the otterbox? I'm clumsy and drop my phone alot. I own the otterbox, which is a tank, and has helped me numerous times, but I have come to accept that the otterbox ruins iphone aesthetics, so I'm looking for a less bulky case that will still provide reasonable protection against occasional drops out of my hand etc. Some of the cases my friends have are so thin I worry it won't do anything.
  • Is the iPhone 5 safe without a case? So I recently got an iphone 5 and an otter box. I feel safe with the otter box because of the great protection, however it doesn't leave a good feel. I personally think the iphone 5 feels awesome and love it without the case. Is it safe without the case from cracks? And if you cracked without the case, how high was the fall, what was it on ect.
  • Is my iphone 5 safe enough without case? It want to use my iphone 5 without a case so i can feel how smooth it is, and how LIGHT it is and is it safe to use it around without a case just a protector screen!
  • Is it still safe to use my IPhone case? Today I went to the beach and I stupidly left my phone in the sun. The edge of my case started peeling! It's a black case that I got from Urban Outfitters (the back is a wooden image of the California flag) and I just wanted to know if it's fine for me to still use it?
