Advice on acid free cartridge bags/loose cartridge protection?

I have recently been interested in purchasing some affordable protection for my SNES/Super Famicom/Genesis cartridges. I understand that universal game cases are the preferred method of protection though i'm fairly tight on money right now and can't really invest in a carton of 100. I also don't really have the room to display/store 100 universal game cases at this time. I was wondering if anyone had experience with the cartridge bags for sale at places like retroprotection.com (http://www.retroprotection.com/product.sc?productId=25&categoryId=3).

These remind me of the bags you'd find in Japan retro game shops that package each individual cartridge in these sorts of bags. Do these do a good job at preventing label wear/dust? They're certainly affordable.

Some advice would be nice. I'd like to protect my loose carts in a reasonably affordable manner.

Thanks everyone!

I use old VHS cases for my loose cartridges, didn't cost me a thing because well we had a lot of VHS tapes to get rid of haha, mind you if you have loose manuals they won't fit in and they probably take up more room than a UGC.
Alternatively I know a guy who uses these or similar for all of his boxed games http://www.ebay.co.uk/itm/25-Small-...UK_Envelopes_Mailing_Bags&hash=item3f166271ff
