I had about 3 YYH cels come in normal cel bags. 
However, in between the sketch and the cel were 
sheets of wax paper.

Now... can anyone tell me if wax paper damages a 
cel (other than giving it a slight wax buildup on 
the paint)?

On a whole other level, the weirdest wrapping I 
got was comic storage bags cut and taped 
together. Not too unusual, but weird enuff. =(
