Iso crystal envelope sleeves (with flap) for 135 negs...

Don't laugh. I've been looking for these for weeks now to no avail. Crystal protective sleeves for 135 negs where you store all 6 or seven stripes of film in one single "envelope" with a flap.
They used to be as common as tea or coffee but not any longe where I live (continental Europe).

I used to buy Panodia stuff but in their infinite "wisdom" they now sell 120 format only.

Renko seems to offer what I want but you can't remove the negs from the top of the envelope you have to slide them from the side... A scratch-prone design maybe?

So if you have any link address to give I'll gladly take them!

What is 'crystal' - a very hard, very heavy, transparent, silica-based mineral?!
[Edit: I have just discovered that "papier cristal" is the French term for glassine, so perhaps the OP is a French-speaker, and this is the material that s/he means?]

I haven't seen envelopes with one section for holding multiple negatives, made of glassine (also known as pergamine, or paper) or translucent plastic, since I was a child and got the box-brownie negs back with all eight in one little packet. There always seemed to be a risk of the negs scratching each other within the envelope, but I suppose that is only when inserting them or removing them. As you have probably found, the usual thing these days is a page having separate channels for sliding in each negative strip.

A more 'museum standard' solution has a separate, flap sealed, vertical loading channel for each neg strip - these would be a 'better' solution as the neg does not need to slide in and out, reducing scratching risks slightly. The ones I saw each cost more than the film inside, which would be justifiable when the images are Elvis and Princess Di, descending from the UFO hand in hand, but I'm too cheapskate for that. However, I do keep 4x5" and 8x10" negs in single-neg glassine envelopes, with the emulsion on the opposite side to the glue seam of the envelope, so perhaps there is hope for me yet.

[Edit 2: The ISO standard applicable to the storage of photographic negatives is HERE. Note that this is the original standard from 2001 and there have been a couple of revisions since then, but to access those costs money.]

Kenro make clear faced bags 10.5 X 13 inches which will do exactly what you want. You can fold the bag over.
Unless of course you are being particularly picky in which case too bad.

They make a 135 bag, 1.75 x 10

I don't think you bothered looking.

ClearBags.com has everything.

Tell them I sent you. They'll say "who?"

Ok let me say that again... How do you file your 135 negs once they're dry? Maybe a solution to my problem will come up if I start with the basics.

PrintFile. I've been using them for ages. They are available in all sizes. www.printfile.com

Readily available from most mail order suppliers.

in Kenro paper neg sheets. Specifically these:

The clear ones seem like a good idea but I promise you that sooner rather than later you will get a neg stick to them and it won't come out without damage which can't be repaired. If by chance they do stick to paper you can wet it and it will come off without damage.

Other makes which may be more readily available in the US should be just as good.
