Query: VERY POOR QUALITY CASES! DO NOT BUY!

I bought several of these 10 packs. After opining one pack some of the cases just fell apart, others were cracked. Out of ten only one didn't break after being opened. The plasic is extremely thin and very flimsy and breaks as soon as you opened them.Do not buy these, look for more quality cases. The quality of these is unexeptable.
