Dear friends,

I decided to put my collection in holders. I read, that the most adequate are holders made of kind of plastich called "Mylar". The problem is, that I live in Poland and I couldn't find information if holders produced by European producers like:

Lighthouse (another called Leuchturm)
Lindner
Hartberger

are made of this material.

Maybe Mylar is name used only in USA ?? I also couldn;t find any company selling holders made of mylar in UK.

Please help me. Thank you in advance,
