So I got a new derasa shipped to me last week. The first day I got it it was open off and on the first day but I was not worried about it due to shipping stress. It closed up and has been closed for the most part. I noticed the the very outside edge of the lip will come out but that's about it. I know its still alive because the lip will go in and out with it. But my question is how long can it go like this before problems with it due to it being closed up for so long?
