[Marcin Cimala]

Hi
I want buy a few od this new membrane frames
http://shop.ebay.de/i.html?_from=R40&_trksid=m570&_nkw=Schweberahmen&_sacat=See-All-Categories

I want to know if they are hermetic the same as this normal membrane boxes. 
Ofcourse out typical membrane boxes, especially the larger are not 100% 
hermetic, but when closed, specimen inside is very well covered from oudside 
humidity. But I never see closer this wooden membrane boxes, so if anyone 
have one please let me know.

I need them for our new hammer Soltmany, to hold samples perfect fresh for 
years.
Please answer to my private email.
