Thanks Jet. My student ID was printed on light blue laminate because they were out of the white laminate because I had it made kind of late. Will thi sstill be valid at a mall J.Crew? Aslo do they have an expiration date or summer amnesty on this? I'll probably just start a new thread to ask.
Whatever you do don't ask in the jcrew thread by all means create a new thread for this or your questions will go unanswered. I believe any expired id will work as long as it's not older than 9 years and you can repair the laminate with red chambray which will entitle you to free alterations to make it fit like boo.
Almost all zippers in this kind of product and in this price range are made from an alloy of copper, zinc, and nickel. The ususal proportions are 5:2:2. I don't think there's a detectable variance from these proportions in either the j. crew or levis zippers.
