Ordered these the other day from Amazon (sorry, on iPod and don't havens link). They feel like Lansinoh bags to me, but what appeals to me is that they are biodegradeable. Although, to be fair, Lansinoh bags are recycleable.
Haven't thawed any milk I've put in them to see if that makes them leak, as I don't need to that milk right now.
Price...comparable to Lansinoh bags, in that the price listed was for 75 bags. I ordered enough stuff that shipping was free.
