Hello!

There's a question I've always wanted to ask 
about cel-bags.

The problem I have with my cel-bags is the 
following:
The adhesive film gets very wavy when I have 
enclosed the cel.
The adhesive film adheres not smooth to the cel-
bag but gets wavy. The result is it doesn't look 
very good if the cel is enclosed because of these 
waves in the bag. I've also noticed that the 
adhesive film is wavy even when I didn't have 
enclosed the cel.

So, I hope my problem was understandable.
Which brand of cel-bags do you use or which can 
you recommend me?
Or is there a trick I don't know how I can manage 
it that the adhesive film adheres smooth?
I've got cels from dealers where this adhesive 
film has adhered smooth and wasn't wavy at all.

I hope someone can help me with this particular 
problem.
