I got it from the Etsy shop FabFabLLC. The one I had for my 5S was from PurlSoho and was definitely a lot sturdier and nicer quality, but this one was pretty nice.
PurlSoho are where I got my 5S one as well thanks for the info *scurries off to Etsy to buy things*
If you haven't already, the seller sent me a message with a discount code. HUGSAREFUN will get you $2 off!
