Good evening!
Hey there I'd love to buy your Iphone 5s 16gb space gray, is it in good condition, not used, and will work well?
It's in excellent condition, not one single scratch on it. It has the original box, charger and a brand new SIM card. If you buy it I'll factory reset it. 
Alright, sounds good. Can you do $150? that seems like a fair price.
